Kilometers per Hour to Meters per Second Converter

Relationship Between Kilometers per Hour and Meters per Second

The conversion between kilometers per hour (km/h) and meters per second (m/s) is based on the relationship where 1 kilometer equals 1000 meters and 1 hour equals 3600 seconds.

1 km/h = 0.277778 m/s

Therefore,

1 km/h = 1/3.6 m/s ≈ 0.277778 m/s

To convert kilometers per hour to meters per second, we divide the value in km/h by 3.6.

For example, 36 km/h equals 10 m/s, and 90 km/h equals 25 m/s.

Kilometer per Hour (km/h)

What is a Kilometer per Hour (km/h)?

Kilometer per hour (symbol: km/h) is a unit of speed in the International System of Units (SI), expressing the number of kilometers traveled in one hour. It is the standard unit for measuring vehicle speeds in most countries worldwide.

History and Origin

The kilometer per hour became widely adopted with the metric system and the rise of automobile transportation. It provides a convenient way to express vehicle speeds using the metric system's base unit of length (kilometer) and the standard unit of time (hour).

Current Use

• Traffic speed limits: Used in most countries for road signs and speed regulations
• Vehicle speedometers: Standard unit displayed on cars, motorcycles, and bicycles in metric countries
• Weather reports: Wind speeds and storm movement speeds
• Sports: Running, cycling, and other athletic performance metrics
• Aviation: Some aircraft speeds, especially at lower altitudes
• Marine navigation: Some boat and ship speeds

Meter per Second (m/s)

What is a Meter per Second (m/s)?

Meter per second (symbol: m/s) is the SI base unit for speed and velocity. It expresses the number of meters traveled in one second. It is widely used in scientific, engineering, and physics applications.

History and Origin

The meter per second became the standard unit for speed in the International System of Units (SI) when the metric system was established. It provides a direct and fundamental measurement of speed based on the base units of length (meter) and time (second).

Current Use

• Physics and engineering: Standard unit for velocity and speed calculations
• Scientific research: Used in experiments and data analysis
• Weather and meteorology: Wind speeds and air velocity measurements
• Sports: Running speeds, especially in track and field events
• Aviation: Aircraft speeds in some contexts
• Marine navigation: Some boat speeds
