how how to change 250 gram into kg​

Answer 1

We know (by definition) that: 1 g = 0.001 kg.

We can set up a proportion to solve for the number of kilograms.

1 g / 250 g = 0.001 kg / x kg

Now, we cross multiply to solve for our unknown x:

x kg = (250 g / 1 g) * 0.001 kg → x kg = 0.25 kg

Conclusion:

250 g = 0.25 kg
