Degrees Celsius per 100 meters to kelvins per kilometer

Type a value in °C/100 m to get it in K/km instantly.

98K/km

That's 3.9× as steep as the geothermal gradient — nothing on our list beats it. Climbing the 3,800 m from Chamonix to the top of Mont Blanc, that is 372.4 °C colder.

What it means

How fast does it cool?

Real lapse rates change with humidity, time of day and weather; inversions make them negative.

The math

How to convert °C/100 m to K/km

To convert degrees Celsius per 100 meters to kelvins per kilometer, multiply by 10.

Example: 9.8 °C/100 m × 10 = 98 K/km.

In the other direction, 1 K/km = 0.1 °C/100 m.
