The following is a list of definitions relating to conversions between feet per second and millimeters per second.
What are feet per second (ft/s)?
Feet per second is a unit of speed in both US Customary Units as well as the Imperial System. It measures the number of feet travelled in a second. The symbol for feet per second is ft/s.
What are millimeters per second (mm/s)?
Millimeters per second is a unit of speed in the Metric System. It measures the number of millimeters travelled in a second. The symbol for millimeters per second is mm/s and the International spelling is millimetres per second.
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|
