When you have conversion factors in your calculations, do you also take the sig figs of those numbers into account? For example, 1L = 1000mL, would you take the sig figs into account when calculating the rest of the problem? Thanks!

No, if the conversion is completely equal, you do not have to consider the sig figs. So in the example you provided, 1000 ml=1 L, you would not consider those sig figs. However, a conversion factor that is not completely equal, such as molar masses, would require you to consider those sig figs.

No, base the sig figs off of the accuracy of information given to you, not known constants. I hope this helps!

No you would not take into account the sig figs of conversion factors like the example you gave. Use the sig figs from the numbers the problem gives you instead.
