Meter per second ( unit symbol : m / s) is the derived unit of speed in the SI system of units . An object moving at a constant speed of 1 m / s travels a distance of one meter in one second .

In everyday life, many speeds are instead given in km / h . The conversion from m / s to km / h is done using the factor 3.6 km / h / m / s.

{\ displaystyle \ mathrm {1 \, {\ frac {m} {s}} = {\ frac {1} {1000}} \, km \ cdot {\ frac {1} {{\ frac {1} {3600 }} \, h}} = 3 {,} 6 \, {\ frac {km} {h}}}}

An easy to remember rule for quickly converting m / s to km / h is: "Times four, minus 10%".
