4.2 w ≈ 4.2 × 10^-9 gw. To convert watts to gigawatts, divide by 1,000,000,000: 4.2 ÷ 1,000,000,000 = 4.2 × 10^-9.
How to convert watts to gigawatts
gw = w × 1 × 10^-9
- 1 w = 1 × 10^-9 gw (and 1 gw = 1,000,000,000 w).
- Multiply the amount by the factor: 4.2 × 1 × 10^-9 = 4.2 × 10^-9.
- Answer: 4.2 w ≈ 4.2 × 10^-9 gw (rounded to 6 significant figures).
Shortcut: dividing by 1,000,000,000 gives the same result as multiplying by 1 × 10^-9.
