# Micrograms to grams

**1 microgram in grams: 1 µg = 0.000001 g**

g = µg × 0.000001

To convert micrograms to grams, multiply by 0.000001. The table below gives the values people look up most often, and the converter works for any number.

| 1 µg | 0.000001 |
| 2 µg | 0.000002 |
| 3 µg | 0.000003 |
| 4 µg | 0.000004 |
| 5 µg | 0.000005 |
| 10 µg | 0.00001 |
| 15 µg | 0.000015 |
| 20 µg | 0.00002 |
| 25 µg | 0.000025 |
| 30 µg | 0.00003 |
| 40 µg | 0.00004 |
| 50 µg | 0.00005 |
| 75 µg | 0.000075 |
| 100 µg | 0.0001 |
| 250 µg | 0.00025 |
| 500 µg | 0.0005 |
| 1,000 µg | 0.001 |

## How the conversion works

The relationship is g = µg × 0.000001. Both units measure mass, so the conversion is a fixed factor that never changes.

## Common questions

### How many grams are in one microgram?

One microgram equals 0.000001 grams. g = µg × 0.000001.

### How do you convert micrograms to grams?

Use g = µg × 0.000001. So 10 µg is 0.00001 g.

### How many micrograms are in one gram?

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