Kelvins per kilometer to degrees Celsius per 100 meters
Type a value in K/km to get it in °C/100 m instantly.
0.98°C/100 m
That's about the same as dry air. Climbing the 3,800 m from Chamonix to the top of Mont Blanc, that is 37.24 °C colder.
Convert the other way: °C/100 m to K/km
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 K/km to °C/100 m
To convert kelvins per kilometer to degrees Celsius per 100 meters, multiply by 0.1.
Example: 9.8 K/km × 0.1 = 0.98 °C/100 m.
In the other direction, 1 °C/100 m = 10 K/km.
