Multiply by the conversion factor: 5 x 2.54
The result is: 12.7 cm/s

About Inch/Second

The inch/second (in/s) is a unit of speed and velocity. One inch/second equals 0.0254 metre per seconds. UnitConvertLab converts it against every other speed unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: speed calculations, engineering and science, education.

About Centimeter/Second

The centimeter/second (cm/s) is a unit of speed and velocity. One centimeter/second equals 0.01 metre per seconds. UnitConvertLab converts it against every other speed unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: speed calculations, engineering and science, education.
