About Lapse Rate Calculator (Formula)

The Lapse Rate is a measure of the rate at which temperature changes with increasing altitude in the Earth’s atmosphere. It is defined as the decrease in temperature per unit of vertical distance.

The formula for calculating the lapse rate is:

Lapse Rate = g / Cp


  • “g” represents the acceleration due to gravity.
  • “Cp” represents the specific heat at constant pressure of the air.

The lapse rate is typically expressed in units of temperature per unit of vertical distance, such as degrees Celsius per kilometer (°C/km) or degrees Fahrenheit per thousand feet (°F/1000 ft). The lapse rate plays a crucial role in meteorology and atmospheric science, as it influences weather patterns and the stability of the atmosphere.
