# Watts to megawatts

**1 watt in megawatts: 1 W = 0.000001 MW**

MW = W × 0.000001

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

## Watts to megawatts table

*Common watt values converted to megawatts.*

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

## How the conversion works

The relationship is MW = W × 0.000001. Both units measure power, so the conversion is a fixed factor that never changes.

## Common questions

### How many megawatts are in one watt?

One watt equals 0.000001 megawatts. MW = W × 0.000001.

### How do you convert watts to megawatts?

Use MW = W × 0.000001. So 10 W is 0.00001 MW.

### How many watts are in one megawatt?

One megawatt equals 1,000,000 watts, which is the reverse of the conversion above.
