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.
