About Converting Centimeter per Seconds to mph
Centimeter per Seconds and mph both describe speed, and the conversion matters whenever a maritime or aviation speed (knots) needs to be compared against a road speed (mph). Specifically: Distance divided by time, and miles per hour.
Formula
mph = centimeter per seconds × 0.0223693629205
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter per seconds equals 0.01 base units, and 1 mph equals 0.44704 base units, so dividing one by the other gives the direct centimeter per seconds-to-mph factor of 0.0223693629205.
Simple example
1 cm/s × 0.02236936292 = 0.0223693629 mph
1 centimeter per seconds = 0.0223693629 mph.
Real-world example
10 cm/s × 0.02236936292 = 0.2236936292 mph
10 centimeter per seconds = 0.2236936292 mph.

Understanding the Centimeter per Seconds (cm/s)
Distance divided by time.
Understanding the mph
mph (mph) measures speed. Miles per hour follows directly from the international statute mile (1,609.344 m) divided by one hour. It is classified as a US/imperial customary unit.
Where it's used: United States (road speed limits and vehicle speedometers) United Kingdom (road speed limits)
Uses of the mph today
- Road speed limits and vehicle speedometers in the US and UK
- Weather reporting (wind speed) in the US
- Sports statistics (e.g. pitch speed, wind gusts) in US media
History of the mph
Miles per hour is a compound unit with no separate origin story of its own — it follows automatically once the statute mile was fixed at 5,280 feet in 1593 and later refined to exactly 1,609.344 meters by the 1959 international agreement that also standardized the pound.
Historical origin. mph was not the invention of a single named person; it developed through the process described above.
mph — sources
- NIST — International yard and pound (1959) — Basis for the modern mile used in mph.
