Speed Conversion

Speed is a fundamental concept in physics that describes how fast an object moves. The meter per second (m/s) is the SI unit of speed, defined as the distance traveled in meters divided by time in seconds.

Common Speed Units

• Meter per second (m/s): The base unit of speed in the International System of Units (SI). One meter per second equals the speed of an object that travels one meter in one second.
• Kilometer per hour (km/h): A metric unit of speed commonly used for vehicle speeds, weather reports, and everyday measurements. One kilometer per hour equals 0.277778 meters per second.
• Mile per hour (mph): An imperial unit of speed commonly used in the United States and United Kingdom. One mile per hour equals 0.44704 meters per second.
• Knot (kt): A unit of speed used in aviation and maritime contexts, equal to one nautical mile per hour. One knot equals 0.514444 meters per second.

Applications

Speed conversions are essential in:

• Transportation: Vehicle speeds, aviation, maritime navigation
• Sports: Athletic performance, racing, and timing
• Weather: Wind speeds, storm tracking, and meteorological data
• Physics: Motion analysis, kinematics, and dynamics
• Engineering: Machine speeds, conveyor systems, and automation

Conversion Examples

• 1 meter per second = 3.6 kilometers per hour (SI to metric unit)
• 1 kilometer per hour = 0.277778 meters per second (Metric to SI unit)
• 1 mile per hour = 1.60934 kilometers per hour (Imperial to metric unit)
• 1 knot = 1.852 kilometers per hour (Nautical to metric unit)
