The standard (SI) unit of speed is meters per second (m/s), but it can also be expressed in other units, such as kilometers per hour (km/h), miles per hour (mph), or feet per second (ft/s), depending on the context or the country's measurement system.
Free online speed converter - converts between 33 units of speed, including meter/second [m/s], kilometer/hour [km/h], mile/hour [mi/h], break, etc. Also, explore many other unit converters or learn more about speed unit conversions.
Aug 21, 2023 · For example, to convert from miles per hour to kilometers per hour you would multiply by 0.44704 then divide by 0.2777778. Or, multiply by 0.44704/0.27777778 = 1.6093439. So, to convert directly from mph to km/h (kph), you multiply by 1.6093439.

Speed is the distance covered in a specified slice of time. Naturally, speed is measured in units of distance divided by units of time. This versatile speed convertersupports conversions between imperial units, between metric units, as well as converts from metric to imperial, and vice versa. You can convert units used for measuring speed such as m...
Since 1959 both metric and imperial units of speed are defined using the standard meter (metre in British English) as a base unit. Consequently, all metric units for measuring velocity are expressed relative to it, e.g. a kilometer is 1,000 meters. To convert between metric units one needs to take into account the length dimension and the time dime...

Easily calculate the acceleration, starting and final speed, or time to reach a given speed with this acceleration calculator. Supported metrics are meters per second, miles per hour, miles per second, km per hour, km per second, yards/feet per second and knots. Output is in meters per second squared and standard gravity (g, g-units).
Jun 6, 2024 · To convert km/h to m/s use the following formula: speed in m/s = speed in km/h * 0.27778. For example, a high-speed TVG train has a top speed of 320 km/h. What's that in m/s? speed of TVG train in m/s = 320 * 0.27778 ≈ 88.9 m/s. To perform the reverse conversion, m/s to km/h, the formula to use is: speed in km/h = speed in m/s * 3.6

Apr 18, 2024 · average velocity = (velocity₁ × time₁ + velocity₂ × time₂ + …) / total time. You should use the average velocity formula if you can divide your route into few segments. For example, you drive a car with a speed of 25 mph for 1 h in the city and then reach 70 mph for 3 h on the highway.
