Significant Figures in Logarithms & Antilogs

Learn how to round log and antilog answers to the correct number of sig figs. There's just one rule: The number of sig figs after the decimal in the calculated log value equals the number of significant figures in the original number. In chemistry, this is useful when doing pH calculations.

This was very helpful, but I wonder, what if there is no number after the decimal in the antilog calculation? Like 10^50. What would be the sig figs?

Thanks mam! It really helped👍👏

[@ChemistryinaNutshell]

You're most welcome. 😊

Do you know where i can find the significant figures rules for trig functions?

[@anoshaiqbal8241]

Outstanding mam❣

[@ChemistryinaNutshell]

Thank you! I'm glad you enjoyed it!

And then you get into grad school and no one cares about sig figs anymore 😂
