Conversion formula

The conversion factor from kilograms to grams is 1000, which means that 1 kilogram is equal to 1000 grams:

1 kg = 1000 g

To convert 400 kilograms into grams we have to multiply 400 by the conversion factor in order to get the mass amount from kilograms to grams. We can also form a simple proportion to calculate the result:

1 kg → 1000 g

400 kg → M(g)

Solve the above proportion to obtain the mass M in grams:

M(g) = 400 kg × 1000 g

M(g) = 400000 g

The final result is:

400 kg → 400000 g

We conclude that 400 kilograms is equivalent to 400000 grams:

400 kilograms = 400000 grams
