When you need to convert meters per second to kilometers per hour

Reading road signs and speed limits abroad.
Comparing running or cycling pace with training plans from another country.
Interpreting wind speeds in forecasts and aviation or marine reports.

Common mistakes to avoid

Dividing when you should multiply. Because 1 meter per second = 3.6 kilometers per hour, the answer should be larger than the number you started with.
Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.

How precise does the answer need to be?

Round only at the end, and only to the precision your task actually needs. The converter above keeps full double precision internally and rounds for display.

How these units are defined

Meter per second (m/s): The SI unit of speed. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
Kilometer per hour (km/h): The road-speed unit in metric countries. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
