Speed & Velocity Converters

About Speed Units

Speed (or velocity in physics) measures how fast an object moves - specifically, the distance traveled per unit of time. Speed units are compound units derived from length and time measurements.

• Kilometer per Hour (km/h): The most common speed unit worldwide, used for road traffic, cycling, and general travel speeds
• Meter per Second (m/s): The SI derived unit of speed, commonly used in physics, engineering, and scientific calculations
• Meter per Minute (m/min): Used for slower speeds like walking pace or conveyor belt speeds

Conversion Formulas

• km/h to m/s: Divide by 3.6 (or multiply by 0.2778)
• m/s to km/h: Multiply by 3.6
• m/s to m/min: Multiply by 60
• m/min to m/s: Divide by 60

Why the 3.6 Factor?

Converting between km/h and m/s requires the factor 3.6 because:

• 1 kilometer = 1,000 meters
• 1 hour = 3,600 seconds
• Therefore: 1 km/h = 1,000 m ÷ 3,600 s = 1/3.6 m/s ≈ 0.2778 m/s

Speed conversions are essential for physics problems, traffic planning, athletics, and understanding motion. Whether calculating travel time, comparing vehicle speeds, or solving physics equations, these conversions help us understand and communicate how fast things move.
