Question

The mass of an object is 100 mg. What is the object's mass in kg? Please show some work to help explain it.

Answer 1

Answer:

0.0001 kg

Explanation:

We know that, 1 kg is equal to 1000000 mg.

Supposing the mass of the object in kg to be x, we can write it as:

1 kg = 1000000 mg

x kg = 100 mg

So to convert mg into kg, we need to divide the mass in mg by 10^6:

x = 100 / 1000000

x = 0.001 kg or 1 × 10^-4kg

Therefore 100 mg is equal to 0.0001 kg of mass.

Answer 2

100 mg

100 * 10^-3 g

0.1 g

0.1 * 10^-3 kg

10^-4 kg

- 1 kg = 1000 g

- 1 g = 1000 mg
