Meter per second (m/s) - Unit Information & Conversion

Definition

Meters per second (m/s) is the base unit of speed and velocity in the International System of Units (SI). It measures the distance in meters traveled in one second.

History

The concept of measuring speed evolved with the development of standardized units for distance (meter) and time (second) within the metric system, established during the French Revolution. The formal adoption of m/s as the SI derived unit for velocity solidified its importance in scientific contexts.

Common Uses

• Physics & Science: The standard unit for speed and velocity in scientific calculations, experiments, and equations (e.g., calculating acceleration, momentum).
• Engineering: Used in various engineering disciplines for specifying speeds of machinery, fluid flow rates, and other technical parameters.
• Athletics: Sometimes used to measure short-distance running speeds (sprints) and throwing velocities in sports science.
• Meteorology: Wind speed is often measured or converted to m/s for scientific models and international reporting, although km/h or knots might be used in public forecasts.
• Technology: Specifying the speed of data transmission or processing components in some technical contexts.

Unit FAQs

What is the SI unit for speed?

Meters per second (m/s) is the base SI derived unit for speed and velocity.

Is m/s used for everyday speeds like driving?

Not typically for driving; kilometers per hour (km/h) or miles per hour (mph) are more common for vehicle speeds. m/s is primarily used in scientific and technical fields.

How does m/s relate to km/h?

1 m/s is equal to 3.6 km/h. To convert m/s to km/h, multiply by 3.6. To convert km/h to m/s, divide by 3.6.
