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

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 gram is equal to 2.5E-6 × 400 kilograms.

Another way is saying that 400 kilograms is equal to 1 ÷ 2.5E-6 grams.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred kilograms is approximately four hundred thousand grams:

400 kg ≅ 400000 g

An alternative is also that one gram is approximately zero times four hundred kilograms.
