Direct Answer

1 km/h = 0.277778 m/s

Formula: m/s = km/h × 0.277778. This page supports instant conversion, reference table checks, and related unit links.

About this conversion

This Koverts page converts kilometers per hour (km/h) to meters per second (m/s) — the standard SI speed for physics equations, wind engineering, and m/s weather reports.

Kilometers per hour (km/h) is the metric unit for road speed in most countries and is common for vehicle dashboards and weather reports outside the US.

Meters per second (m/s) is the SI base combination for speed and appears in physics formulas, building wind codes, and scientific datasets.

Typical uses

  • Physics homework: kinematics uses m/s
  • Wind speed: many forecasts give m/s alongside km/h
  • Engineering and safety limits expressed in m/s
  • Converting dashboard km/h to m/s for quick mental checks
Formulam/s = km/h × 0.277778

Common reference values

  • 1 km/h = 0.277778 m/s
  • 10 km/h = 2.77778 m/s
  • 100 km/h = 27.7778 m/s

Tip: Divide km/h by 3.6 to get m/s (or multiply by 5/18). So 72 km/h ÷ 3.6 = 20 m/s.

Did you know? The factor 3.6 comes from 1000 meters per kilometer divided by 3600 seconds per hour — 1000/3600 = 1/3.6.

Educational reference — always verify critical measurements (medical, engineering, legal) with primary sources.

How to convert

Km/hour (km/h) → Meters/sec (m/s)

To convert from Km/hour (km/h) (km/h) to Meters/sec (m/s) (m/s)，multiply your value by 0.277778.

m/s = km/h × 0.277778

For example，10 km/h = 2.77778 m/s.

// Frequently Asked Questions

Is m/s faster or slower than km/h numerically?▼
For the same speed, the number in m/s is smaller than in km/h because each m/s is 3.6 km/h. Example: 10 m/s = 36 km/h.
Why do physics problems use m/s instead of km/h?▼
SI base units combine meters and seconds, so m/s matches the meter-kilogram-second system used in formulas. km/h is convenient for everyday driving speeds.
What is 1 km/h in m/s?▼
1 km/h = 0.277778 m/s.
How is the conversion calculated?▼
m/s = km/h × 0.277778.
Can I convert other values?▼
Yes. Use the converter box above to enter any value and get instant results.
