thank you, you saved me!!

helpful! and cute cat ;)

why did you decide to use just 1 significant figure if your measurements have 2 significant figures? thank you.

Hi, only ONE significant figure (the last one) should be uncertain. Had I left 0.58 +- 0.18, the 5 and the 8 in the average would be not certain (changed by the uncertainty)... therefore I had to round the average to 1 SF (0.6).... Then rounding the uncertainty to the same digit (that one is not really a rule, but stating 0.6 +- 0.18 is just weird.).
With 0.6 +- 0.2 the message of significant figures matches the one of uncertainty...meaning my cat could be anything from 0.4 to 0.8m. Two SF, 0.58 would mean 0.50 to 0.60, what with the given measurements and calculated uncertainty is not true.
