# 2.70 g/cm^3 converted to kg/m^3

for my answer on my calculator I get 2700 g/m^3     But I’m not sure if I write 270. g/m^3 as my final answer because of the rounding to the least significant figure rule which we started with 2.70 g/cm^3 which is 3 sig figs, so I would think the answer needs the same amount of sig figs hence 270. g/m^3. Do we use the least sig fig rule in this conversion? Why or why not?
