221 w = 0.221 kw. To convert watts to kilowatts, divide by 1,000: 221 ÷ 1,000 = 0.221.
How to convert watts to kilowatts
kw = w × 0.001
- 1 w = 0.001 kw (and 1 kw = 1,000 w).
- Multiply the amount by the factor: 221 × 0.001 = 0.221.
- Answer: 221 w = 0.221 kw.
Shortcut: dividing by 1,000 gives the same result as multiplying by 0.001.
