Converting Minutes to second in sig figs

swiftjab · Sep 8, 2009

2.05 min multiplies 60 sec/1 min= 100 not 123 right? Since 60 has only one sig fig, is it okay to write it as 60.00 to get a more accurate answer?

Since 60sec/1min is a definition it doesn't follow the "sig fig" rules, they only apply for measurements. it's 123 sec.

Since you brought it up, does the "2" in V=v0 + 2at follow the sig fig rule?
