Metres per second to Kilometres per hour
1 metre per second = 3.6 kilometres per hour · 1 km/h = 0.27778 m/s
1 metre per second = 3.6 kilometres per hour
How it’s calculated
km/h = m/s × 3.6
- Multiply the value in metres per second by 3.6.
- To go back, divide by 3.6 (or multiply by 0.2777777778).
- 1 m/s = 3.6 km/h · 1 km/h = 0.2777777778 m/s

Find the conversion factor
By definition 1 m/s = 3.6 km/h. Source: BIPM SI Brochure (9th ed.) (SI prefixes and accepted units).
Multiply by the factor written as a fraction
Put m/s in the denominator so it cancels, leaving km/h.
Calculate (unrounded)
Round the answer
Rounded to 5 significant figures.
Answer: 3.6 km/h
1 m/s in other units
Batch convert m/s → km/h
- 1 m/s = 3.6 km/h
- 5 m/s = 18 km/h
- 10 m/s = 36 km/h
- 25 m/s = 90 km/h
Quick examples
- 1 metre per second = 3.6 kilometres per hour
- 5 metres per second = 18 kilometres per hour
- 10 metres per second = 36 kilometres per hour
- 25 metres per second = 90 kilometres per hour
- 100 metres per second = 360 kilometres per hour
