421 w = 0.000421 mgw. To convert watts to megawatts, divide by 1,000,000: 421 ÷ 1,000,000 = 0.000421.
How to convert watts to megawatts
mgw = w × 0.000001
- 1 w = 0.000001 mgw (and 1 mgw = 1,000,000 w).
- Multiply the amount by the factor: 421 × 0.000001 = 0.000421.
- Answer: 421 w = 0.000421 mgw.
Shortcut: dividing by 1,000,000 gives the same result as multiplying by 0.000001.
