Reading Decimals in the Shop

- A lot of people struggle when it comes to reading decimals like we do in the shop so give this video a watch and further your understanding of reading and pronouncing decimals.
I believe we all are taught decimals differently in school and this is why it's confusing. .1=1 tenth. .01= 1 hundredth. .001= 1 thousandth. .0001=1 10thousandths. Your video was helpful. Now I gotta break my programming from school and I'll be ok.
Joe M. The teachers in school don’t understand what they are teaching
Thats how i understand it too. Im 40 and confused.
Me too. I always did decimal this way
@@erikmc6385 Same here, I’m 39… in machining school and very confused… it’s like a totally different way to talk decimals.
Then it goes microns, millionths
People speak of school but I'm self taught using the metric system and now have a job that uses the imperial measurements system. This video is exactly the confirmation I needed. Thank you! God Bless!
Pretty good stuff. I have to explain this to a lot of my Students when they’re learning how to Tig weld. We set amperage for sheet metal based off material thickness. One amp for every thousandth of an inch. Stainless steel gets two thirds less heat so the thickness multiplied by .7 and take that number. You’d be surprised how many welding instructors don’t know this.
School decimal and machinist decimals really contradict each other and confusing, but this help clarify it very well
.7 is 7/10ths and is "equal" to or the "same" as 700 thousandths or .700. But it's not correct to call .7 as 700 thousandths. To "call" a number as thousandths it must be written with at least three places past the decimal. Example .700 is 700 thousandths, .070 is 70 thousandths, .007 is 7 thousands. The forth place past the decimal is tenths of a thousandth.
Welcome to a machinists world where we throw caution to the wind and call it tenths at the forth place.
could you please explain why the decimal place value is different.
this definitely brought more clarity. thank you. 8/10/24
Awesome! This really helped me, thank you.
Regardless, you did an outstanding job!
I always thought the first spot after a decimal was a tenth, and then a hundredth, and then a thousandth.
I guess I was taught really wrong 😂. I'm a re tard apparently 🤣.
Thank you 🙏
Trust me I thought I was losing it. That is the correct way whenever dealing with math. However when dealing with machining, it is the opposite. After learning it the math way for 29 years, this is somewhat difficult to remember.
I work in a machine shop as well, I do milling and I'm just learning this shit and it's confusing AF 😂.
So if .0001 is a tenth of an inch and .100 is one hundredth of an inch and ten of them make an inch. How is .0001 a tenth (meaning 10 of them make an inch) when it doesn't 😂.
Fkn retarded man .
I'm learning tho man, take er easy ✌️.
Most Machinists and engineers use thousandths of inches as a baseline for measurements. The next reference is millionths(.000001) Works the same.
Thank you. That’s what I was missing, the baseline
which is how you would measure my penis
So the more zeroes/digits the smaller the diameter?
Question ? how many thousands of an inch fit in 1/64th of a inch And how many Thousands of an inch are in 1 mm exactly ?
To know the thousandths you just have to divide the fraction into the constant 25.4mm or which is equal to 1 inch.
example: 1/64, 1 ÷ 64 = 0.015625 inches,
and
1mm = 1 ÷25.4 = 0.039370078740157 inches
And if you want to know how many millimeters are equivalent to inches, you just have to multiply the constant by the thousandths. example .250 inches:
.250x25.4= 6.35 mm
Is he doing this backwards or am I wrong I feel like .1 is 1/10 of an inch right?
It is, he’s right and your right. Just think about it a bit more you’ll get it.
@@MrCococda in no world is .0001 a tenth!
It's 1 tenth of a thousand .@@PiggiesnPuppies
Then I would explain which is bigger and why....everyone would get it if they didn't pay attention in school or do alot of math...and practical aplication...good show
Thanks very much for the video i really appreciate it.
This is why I'm just gonna stick with glorious metric numbers.
If someone said make a .01 ten thousands of an inch adjustment for the lathe would you type that as .01 or .001?
Thanks a lot really helped 💯
Why does this exist? We already had terms for these...
A really good explanation for laymen would be think of a clock ticking off time, the numbers turn the next one
Good explanation 👍🏻👍🏻👍🏻
wow so easy, thank you!!
Thx needed this💯
Helped a ton thank you !!!!
Thanks a lot really helpfull
I graduated cnc school few months ago and they never even teached about the tenths colum so my boss said forget every thing you learned in school so i have truble with tolerance being corect so if he was like ad .01 thousands in the machine im not shure if i should put .01 or .001 to correct same with hundreds so if i had to put 5 thousands in the lathe i think i put .005 but im not shure any tip?
What are you talking about?
0.1 X 10 = 1 which means that 0.1 is one-tenth of 1 by the literal mathematical definition of what 1 is. IDK who you learned this math from, but its 100% wrong. Case in point, what would 1 millionth of an inch be written as? According to this video’s logic 1 millionth of an inch must be written as "1.0" since theres nowhere for the millionths place to be indicated other than the other side of the decimal.
Edit: On talking with some other people I think what's really confusing about this explanation is that you have .0001 indicated as "a tenth" instead of just saying a ten thousandth or at least having that in parentheses. Referring to any fraction as if it had 3 decimal places like you did when you said that 1.5 would be spoken as 1 inch and 5 hundred thousandths of an inch @3:26 , is also a very nebulously communicated idea.
this is so fckin backwards from what we're taught in school...
Thank you
The problem with using the standard fractional measurements in the USA with decimals is that decimals is in the metric system and USA uses fractional measurements as 1/2 or 1/4 and when you use them together they are not very accurate. Its better to either stick to fractional measurements from 1 inch to 1/64ths of an inch or use metric which is 1cm to .00001cm or below.
Thanks for the video. So when you're reading measurements in a machine shop, it's all more or less commonly based off of thousandths? So people will usually not refer to say .25 as a quarter of an inch, it will be 250 thousandths? And like the other example you gave, since .0001 would be one-tenth, would say .0005 be "one-half"?
.0005 five tenths
.0005 could also be called “half a thou”
1/4" = one quarter of an inch...
Not .25
are there like any quizlets or anything that i can use to help me practice
love the bills hoodie

1 ten thousandths is way smaller than a tenth of an inch... . 00013 would be thirteen hundred thousands
Yeah... That's what I was thinking. Isn't this guy backwards?
Depends on if you are in grade school or in a machine shop. Shop speak refers to thousandths of an inch. Saying thirteen tenths like he did is short for saying thirteen ten thousandths
Got one for converting fractions to decimals??
I I know I'll be here for a while 👓
Ok but 2/10ths of an inch is also 1/5th of an inch, it is not 0.0002
A "tenth" means 1 part out of 10
thnx شكرا
How would you read this numbers,
0.1023
0.105
“A hundred 5 thousandths” and “a hundred 2 thousandths and 3 tenths “ I believe
@@detroit1018 I would agree.
Go bills!
What about something like .0013? Thirteen tenths?
you would say 1 thou and 3 tenths
There can’t be thirteen tenths. Tenths only go up to .0000-.0009. Thousands only go up to .001-.009. Ten thousands only go up to .01-.09. Hundred Thousands only go up to .100-.900. The number before going to one inch would .9999 or Nine Hundred Ninety Nine Thousands and Nine Tenths.
@@Matthew-tv3fz Not true. You say one thou three tenths but it's the same as 13 tenths you just do not say it like that in shop math. It's like having .00005. You say 50 millionths of an inch.
It is not 13 tenths as the fourth decimal place is not tenths but is ten thousandths of an inch, therefore you have 13 ten thousandths of an inch, or one ten thousandth of an inch x 13
Bills mafia 💪🏼
I already read the last as "1 ten thousandths".
. 0001 is 1 ten thousandths
you confuse me at .045 how come there is a zero in front of .045 but not .50
is that because a half an inch is actually 500 and 45 is just 45
.045 Is 45 thousandths and .5 is 5 hundred thousandths. The zero at the end of .50 changes nothing and is not needed
@@junkaccounts1504 thank you brother
Sorry but 0.0001 is not 1 tenth that would be 0.1
You should teach this for people who live in this century and use the metric system
YOU ARE A FUCKING GOD
S/O dude
Tenths, hundredths, thousandths,...
Isn't 1 tenth of an inch. .1
No that’s one hundred thousandths of a inch
It’s simple Dave,
.1 is called out as “one hundred thou”.
Or as “one hundred thousandths of an inch”
The simple way to think of it is to imagine if you had 10 mic shims measuring one hundred thousandths a piece that were all stacked up. They would be exactly 1 inch tall, therefore individually you would never refer to them as “a tenth per shim” because that would be much smaller than an inch.
Hope that helps bud.👍🏻
0.1 is read “One Tenth” of an inch, not hundred thousandth.
0.00001 is read “One Hundred Thousandth” of an inch.
Tenths, hundredths, thousandths, ten thousandths, hundred thousandths.
@@bryanteverett8421 I thought I was missing something or it was a joke...but this is all wrong
1/10 is the same thing as 100/1000 , hundred thousandths. Just like 1/2 is the same as 500/1000
You made a statement, now prove it.
100 ÷10=10
10÷10=1
1÷10=.1 tenths
.1÷10=.01 hundredths
.01÷10=.001 thousandths
Help iam a CNC apprentice who sucks at math!!
I just started school for machining and I also suck at math.
What kind of math do you need for work?
Go bills
uhhhh, Im not sure why your calling .5 5,000ths, its 5/10ths.
because its the thousandths place, .008
Sum ting wong
But why
Don't bother asking. You are much better off collecting your blueprints and/or your workpieces and walking out the door. Anyone in need of machine shop services probably has too much money, time, and effort invested in their project to stand there and listen to this nonsense.
Go somewhere where you can have clear and proper communication; a place you can trust to handle your project with competence.
Make a longer video if u can
*thousandths
How you going to teach people basics and can't spell
Okay okay my cell tech isn't fucking stupid. Y'all just change your base number.
