# 90 K to °C

**90 kelvin in degrees Celsius: 90 K = -183.15 °C**

°C = K − 273.15

90 kelvin is -183.15 degrees Celsius. To get there, use °C = K − 273.15.

## How the conversion works

The relationship is °C = K − 273.15. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.
