This table provides a summary of the Speed units within their respective measurement systems.

Unit Symbol Measurement System Description
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
