Conversion formula
The conversion factor from grams to kilograms is 0.001, which means that 1 gram is equal to 0.001 kilograms:
1 g = 0.001 kg
To convert 2.5 grams into kilograms we have to multiply 2.5 by the conversion factor in order to get the mass amount from grams to kilograms. We can also form a simple proportion to calculate the result:
1 g → 0.001 kg
2.5 g → M(kg)
Solve the above proportion to obtain the mass M in kilograms:
M(kg) = 2.5 g × 0.001 kg
M(kg) = 0.0025 kg
The final result is:
2.5 g → 0.0025 kg
We conclude that 2.5 grams is equivalent to 0.0025 kilograms:
2.5 grams = 0.0025 kilograms
Alternative conversion
We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilogram is equal to 400 × 2.5 grams.
Another way is saying that 2.5 grams is equal to 1 ÷ 400 kilograms.
Approximate result
For practical purposes we can round our final result to an approximate numerical value. We can say that two point five grams is approximately zero point zero zero three kilograms:
2.5 g ≅ 0.003 kg
An alternative is also that one kilogram is approximately four hundred times two point five grams.
