# Micrograms to kilograms

**1 microgram in kilograms: 1 µg = 1 × 10^-9 kg**

kg = µg × 1 × 10^-9

To convert micrograms to kilograms, multiply by 1 × 10^-9. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is kg = µg × 1 × 10^-9. Both units measure mass, so the conversion is a fixed factor that never changes.

## Common questions

### How many kilograms are in one microgram?

One microgram equals 1 × 10^-9 kilograms. kg = µg × 1 × 10^-9.

### How do you convert micrograms to kilograms?

Use kg = µg × 1 × 10^-9. So 10 µg is 1 × 10^-8 kg.

### How many micrograms are in one kilogram?

One kilogram equals 1,000,000,000 micrograms, which is the reverse of the conversion above.
