40 mps ≈ 144 kph. To convert metres per second to kilometres per hour, multiply by 3.5999971: 40 × 3.5999971 = 144.
How to convert metres per second to kilometres per hour
kph = mps × 3.5999971
- 1 mps = 3.5999971 kph (and 1 kph = 0.277778 mps).
- Multiply the amount by the factor: 40 × 3.5999971 = 144.
- Answer: 40 mps ≈ 144 kph (rounded to 6 significant figures).
