Convert Kilometers per Hour to Meters per Second - Speed Converter

This converter transforms speed measurements from Kilometers per Hour to Meters per Second, enabling translation of practical speeds to physics-based calculations.

Everyday speeds are naturally expressed in km/h, while physics equations use m/s. This conversion is essential for scientific analysis of motion.

This converter uses the precise relationship where 3.6 km/h equals exactly 1 m/s.

Quick reference table

Kilometers per HourMeter per Second
1 km/h0.28 m/s
5 km/h1.39 m/s
10 km/h2.78 m/s
25 km/h6.94 m/s
50 km/h13.89 m/s
100 km/h27.78 m/s

Methodology

3.6 km/h = 1 m/s. To convert km/h to m/s, divide by 3.6. For example, 36 km/h = 10 m/s, 72 km/h = 20 m/s, 90 km/h = 25 m/s.

Vehicle speeds measured in km/h must be converted to m/s for physics problem analysis. Understanding both units enables practical-to-scientific translation.

Impact calculations, projectile motion, and fluid dynamics all require speeds in m/s. Converting from km/h enables these calculations.

This converter provides precise speed conversions for physics, engineering, and scientific applications.

Worked examples

Example 1 – Car speed: 36 km/h = 10 m/s, typical local speed limit.

Example 2 – Highway speed: 100 km/h = 27.8 m/s, high-speed travel.

Example 3 – Wind speed: 45 km/h = 12.5 m/s, strong wind conditions.

Expert Q&A

What is the conversion from km/h to m/s?

Divide km/h by 3.6 to get m/s. Alternatively, multiply km/h by 0.2778.

Why convert speeds to m/s?

Physics equations use SI units (m/s). Converting enables proper calculation of forces, energy, and motion.

What are everyday speeds in m/s?

Walking: 1.4 m/s; Jogging: 3 m/s; Cycling: 6-8 m/s; Driving: 15-30 m/s.
