  • Precision and relevance may vary depending on the scientific or engineering application

Frequently Asked Questions

What does millimeter per hour measure?
Millimeter per hour is a speed unit representing very slow linear changes, often used to quantify slow depth or motion rates.

Where is kilometer per second commonly used?
Kilometer per second is widely used to express very fast speeds such as those of spacecraft, satellites, and astronomical objects.

How do I convert mm/h to km/s using this tool?
Input the value in millimeter per hour, select the target unit kilometer per second, then convert to get the equivalent speed.

Key Terminology

Millimeter per hour [mm/h]
A unit of speed indicating a change of one millimeter every hour, used for very slow movements or changes.
Kilometer per second [km/s]
A speed unit describing how many kilometers are traveled in one second, used for very fast velocities in aerospace and astronomy.
Conversion Rate
The numerical factor used to change a measurement from one unit to another—in this case, 1 mm/h equals 2.7777777777778e-10 km/s.
