What is kilometers per second (km/s)?

Kilometers per second is a unit of Speed or Velocity in the Metric System. It measures the number of kilometers traveled in a second. The symbol for kilometers per second is km/s and the International spelling for this unit is kilometres per second. There are 0.001 km/s in mm/ms.

What is millimeters per millisecond (mm/ms)?

Millimeters per millisecond is a unit of Speed or Velocity in the Metric System. It measures the number of millimeters traveled in a millisecond. The symbol for millimeters per millisecond is mm/ms and the International spelling for this unit is millimetres per millisecond. There are 1,000 mm/ms in km/s.

caretConversion Formula

The formula to convert from km/s to mm/ms is:

mm/ms = km/s x 1,000

Kilometers per second to Millimeters per millisecond Conversion Example

Task: Convert 75 kilometers per second to millimeters per millisecond (show work)

Formula:
km/s x 1,000 = mm/ms

Calculations:
75 km/s x 1,000 = 75,000 mm/ms

Result:
75 km/s is equal to 75,000 mm/ms
