What is Atmospheric Properties Calculator?

Atmospheric Properties Calculator computes conditions of the atmosphere, airspeed conversions, and basic aerodynamic quantities on a reference body. The calculator is based on methods documented in the official U.S. Standard Atmosphere 1976. This version includes the lower atmosphere below an altitude of 53.4 miles (86 km). The user interface allows conversions between common units in the English and Metric systems.

What are input parameters to get output?

It takes Altitude, Speed and reference length as input to get various output.
