The base unit for speed is meters per second (Non-SI Unit)

[Kilometers Per Hour] symbol/abbrevation: (km/h)

[Millimeters Per Second] symbol/abbrevation: (mm/s)

1 km/h = 277.778 mm/s.

1 x 277.778 mm/s =

Always check the results; rounding errors may occur.

In relation to the base unit of [speed] => (meters per second), 1 Kilometers Per Hour (km/h) is equal to 0.277778 meters-per-second, while 1 Millimeters Per Second (mm/s) = 0.001 meters-per-second.
