Understanding the Speed Units
This table provides a summary of the Speed units within their respective measurement systems.
|inches per second||in/s||US Customary Units (and Imperial)|
|feet per second||ft/s||US Customary Units (and Imperial)||1 ft/s = 12 in/s|
|yards per second||yd/s||US Customary Units (and Imperial)||1 yd/s = 3 ft/s|
|miles per second||mi/s||US Customary Units (and Imperial)||1 mi/s = 1760 yd/s
1 mi/s = 5280 ft/s
|millimeters per second||mm/s||Metric System||1000 mm/s = 1 m/s|
|centimeters per second||cm/s||Metric System||100 cm/s = 1 m/s
1 cm/s = 10 mm/s
|decimeters per second||dm/s||Metric System||10 dm/s = 1 m/s
1 dm/s = 10 cm/s
|meters per second||m/s||Metric System||1 m/s = 1000 mm/s
1 m/s = 100 cm/s
1 m/s = 10 dm/s
|kilometers per second||km/s||Metric System||1 km/s = 1000 m/s|
