What does mile per second [mi/s] represent?

A mile per second is a unit of speed equal to one statute mile traveled in one second, exactly 1609.344 meters per second, and is used to describe very high speeds.

Why is this conversion useful in aerospace engineering?

It helps relate familiar Earth-based speed units to critical orbital velocities used for spacecraft mission design and orbital mechanics analysis.

How to Convert from Mile/second [mi/s] to Cosmic velocity - first?

Q: What is the first cosmic velocity?

It is the minimum tangential speed required at a specific radius from a celestial body's center to maintain a stable circular orbit.

Convert speed values from mile per second (mi/s) to the first cosmic velocity, the minimum speed for stable orbit, using this easy-to-follow guide and converter tool.

Useful for understanding orbital speed requirements in spacecraft mission planning.
Browser-based and easy to use without the need for complex calculations.
Supports high-speed velocity conversions relevant to aerospace and celestial mechanics.

Examples

5 Mile/second [mi/s] converts to approximately 1.018572152 Cosmic velocity - first.
10 Mile/second [mi/s] converts to roughly 2.037144304 Cosmic velocity - first.

Common Use Cases

Describing speeds of spacecraft during orbital insertion and mission planning.
Calculating minimum orbital speeds needed for low Earth orbit and other celestial bodies.
Analyzing the velocity of meteoroids or spacecraft during re-entry or impact scenarios.

Tips & Best Practices

Confirm the context of your speed measurements to ensure mile per second units are appropriate.
Remember that the first cosmic velocity varies based on the celestial body and orbital altitude involved.
Use this tool to gain clearer insights into orbital velocity thresholds for mission design.

Limitations

The first cosmic velocity depends on the gravitational parameter and distance from the body's center and varies by celestial body.
Converting by a fixed factor assumes standardized conditions and may not be accurate for all orbital environments.
Mile per second is not a common unit in aerospace contexts that typically use meters or kilometers per second.
