What units does this speed converter include?
It covers Meters per Second, Kilometers per Hour, Miles per Hour, Knot, Feet per Second — 5 units in total. Every conversion runs through the meters per second as the common reference, so any pair you pick stays consistent with every other pair.
How does this speed converter work?

How accurate are the results?
The factors come from the official definitions of the units (for example, 1 inch is exactly 0.0254 meters and 1 pound is exactly 0.45359237 kilograms), so conversions are as accurate as the definitions themselves. Display rounding to six significant figures can hide trailing digits on extreme values.
