Speed (or Velocity) is a fundamental concept in physics and engineering, representing the rate at which an object covers distance over a given time period. Whether you're an aspiring scientist, engineer, or simply curious about the world around you, understanding and converting between different speed units is an essential skill. In this article, we will explore various units of speed, their definitions, and provide a handy speed converter tool for quick and accurate conversions.
Definition of Speed (Velocity)
Speed, often used interchangeably with velocity in physics, refers to the rate at which an object moves through space. It is calculated by dividing the distance covered by the time taken to cover that distance. Speed is a scalar quantity, meaning it has magnitude but no direction, whereas velocity is a vector quantity, incorporating both magnitude and direction.
Units of Speed (Velocity)
Let's now dive into the different units of speed:
Meter/second (m/s) - Meter/second is the SI unit for speed and represents the distance covered in meters per second.
Conversion factors: 1 m/s = 3.6 km/h = 2.23694 mi/h = 3.28084 ft/s = 1.94384 knots = 1.9426 knots (UK) = 0.00293858 M = 0.06 km/min = 60 m/min
Kilometer/hour (km/h) - Kilometer/hour measures the distance covered in kilometers per hour.
Conversion factors: 1 km/h = 0.277778 m/s = 0.621371 mi/h = 0.911344 ft/s = 0.539957 knots = 0.539612 knots (UK) = 0.000816297 M = 0.016667 km/min = 16.6667 m/min
Mile/hour (mi/h) - Mile/hour represents the distance covered in miles per hour.
Conversion factors: 1 mi/h = 0.44704 m/s = 1.60934 km/h = 1.46667 ft/s = 0.868976 knots = 0.868421 knots (UK) = 0.00131357 M = 0.026822 km/min = 26.8224 m/min
Foot/second (ft/s) - Foot/second denotes the distance covered in feet per second.
Conversion factors: 1 ft/s = 0.3048 m/s = 1.09728 km/h = 0.681818 mi/h = 0.592484 knots = 0.592105 knots (UK) = 0.00089571 M = 0.018288 km/min = 18.288 m/min
Knot (kt) - Knot is a unit of speed used in navigation and aviation, representing nautical miles per hour.
Conversion factors: 1 knot = 0.514444 m/s = 1.852 km/h = 1.15078 mi/h = 1.68781 ft/s = 0.99936 knots (UK) = 0.00151178 M = 0.030867 km/min = 30.8666 m/min
Knot (UK) (kt) - Knot (UK) is a unit of speed used in navigation and aviation in the United Kingdom, representing UK nautical miles per hour.
Conversion factors: 1 knot (UK) = 0.514773 m/s = 1.853184 km/h = 1.151515 mi/h = 1.68889 ft/s = 1.00064 knots = 0.00151275 M = 0.030886 km/min = 30.8864 m/min
Mach (M) - Mach (speed of sound) is a unit of speed that represents the ratio of an object's speed to the speed of sound in the surrounding medium.
Conversion factors: 1 M = 340.29 m/s = 1,225.04 km/h = 761.21 mi/h = 1,116.44 ft/s = 661.47 knots = 661.05 knots (UK) = 20.42 km/min = 20,417.4 m/min
Speed of Light - The speed of light is a universal constant denoting the speed at which light travels in a vacuum.
Conversion factors: Speed of Light = 299,792,458 m/s = 1,079,252,848.8 km/h = 670,616,629.4 mi/h = 983,571,056.4 ft/s = 582,750,421.8 knots = 582,377,603 knots (UK) = 880,991.1 M = 17,987,547.5 km/min = 17,987,547,480 m/min
Kilometer/minute (km/min) - Kilometer/minute measures the distance covered in kilometers per minute.
Conversion factors: 1 km/min = 16.6667 m/s = 60 km/h = 37.2823 mi/h = 54.6807 ft/s = 32.3974 knots = 32.3967 knots (UK) = 0.0489778 M = 1,000 m/min
Meter/minute (m/min) - Meter/minute denotes the distance covered in meters per minute.
Conversion factors: 1 m/min = 0.0166667 m/s = 0.06 km/h = 0.0372823 mi/h = 0.0546807 ft/s = 0.0323974 knots = 0.0323767 knots (UK) = 0.000048978 M = 0.001 km/min
