15 ft/h = 15 × 1.07173037974684e-08 None = 1.60759556962025e-07 None
Foot/hour to Cosmic Velocity - First Conversion Table
| foot/hour | Cosmic velocity - first |

Foot/hour
Foot per hour (ft/h) is a unit of speed representing the distance of one foot traveled in one hour.
History/Origin
The foot per hour has historically been used in engineering and construction to measure slow speeds, especially in contexts where imperial units are standard. Its usage has declined with the adoption of metric units and more common speed measurements like meters per second or miles per hour.
Current Use
Today, foot per hour is rarely used in practical applications but may still appear in specialized fields such as certain engineering, construction, or scientific contexts where imperial units are maintained.
Cosmic Velocity - First
Cosmic velocity - first, also known as Earth's escape velocity, is the minimum speed needed for an object to escape Earth's gravitational influence without further propulsion.
History/Origin
The concept of escape velocity was developed in the early 20th century as part of classical mechanics and gravitational theory, with initial calculations by Sir Isaac Newton and later refinements through modern physics.
Current Use
It is used in aerospace engineering and astrophysics to determine the minimum speed required for spacecraft to leave Earth's orbit and travel into space without additional propulsion.
