Planets - Calculate Surface Temperature

Calculator for the mean surface temperature on Earth, Moon, Sun and planets, in Kelvin, degrees Celsius (centigrade), Fahrenheit and compared to each other. The temperature on a planets' surface depends mostly on its distance from its star (Sun) and from the composition of its atmosphere (particularly by greenhouse gases like CO₂). On planets without an atmosphere, especially on Mercury, if differs extremely between day and night side. When compared to each other, to make a statement like 'on one planet, it is x times as warm as on the other', the ratio of the Kelvin values must be taken, because only the Kelvin temperature scale has a true zero.

Round to decimal places.

Please enter one value, the other values will be calculated.

Example: on Venus, with its temperature of more than 460 degrees Celsius (737 K, 867° F), it is 2.56 times as hot as on Earth with its 15 degrees Celsius (288 K, 59° F), because 737 / 288 = 2.56.
