What Is This Tool?
This tool converts speed values from foot per minute (ft/min), an imperial linear speed unit, into the first cosmic velocity, which is the minimum orbital speed needed for a stable circular orbit around a celestial body. It helps link practical speed measurements to space mission design metrics.
How to Use This Tool?
-
Enter the speed value in foot/minute.
-
Select foot/minute as the source unit and first cosmic velocity as the target unit.

-
Useful for spacecraft mission design and orbital speed calculations.
Examples
-
1000 foot/minute equals approximately 0.0006430 first cosmic velocity.
-
5000 foot/minute equals approximately 0.003215 first cosmic velocity.
Common Use Cases
-
Specifying elevator travel speeds in building engineering using ft/min.
-
Setting conveyor belt speeds in manufacturing measured in ft/min.
-
Calculating the minimum orbital speed for low Earth orbit missions.
-
Designing launch vehicle profiles to reach stable circular orbits.
-
Estimating orbital speeds around the Moon for lunar mission planning.
Tips & Best Practices
-
Understand that first cosmic velocity represents ideal orbital speed, not everyday ground speeds.
-
Use this conversion when relating terrestrial speed units to orbital parameters in aerospace contexts.
-
Consider the very small numeric results when converting from foot/minute to cosmic velocity.
-
Always verify that orbital speed interpretation fits your application context.
-
Leverage this conversion in early spacecraft mission design for planning orbital insertions.
Limitations
-
First cosmic velocity is an idealized orbital speed dependent on gravitational conditions, not for general speed measurement.
-
Foot/minute measures much lower ground speeds compared to orbital velocities, so converted values are extremely small.
-
Requires knowledge of orbital mechanics to properly interpret converted values.
-
Not suitable for applications outside aerospace or astrodynamics contexts.
