Question

In an experiment, you find the mass of a cart to be 250 grams. What is the mass of the cart in kilograms?

Answer 1

It should be 0.25kg because you converter from g to kg and since 1g<1kg so you move the decimal to the left

Answer 2

The answer is:  0.25 kg  .

250 g * ( 1 kg / 1000 g) = (250/ 1000) kg = 0.250 kg = 0.25 kg .
