Black Hole Temperature Calculator

Find the Hawking temperature of a black hole.

Hawking temperature (K) 0

Formula: T = ħc³ ÷ (8π·G·M·k_B)

Step-by-step with your numbers:

1. Values used:

2. Mass = 1 M☉

4. Hawking temperature = 0K

Did we solve your problem today?

Black holes emit faint Hawking radiation with a temperature set by their mass.

The math behind it

T = ħc³ ÷ (8π·G·M·k_B). Smaller black holes are hotter; large ones are extraordinarily cold.

One solar mass → about 6 × 10⁻⁸ K.

Why so cold?

Temperature is inversely proportional to mass, so stellar black holes are far colder than space.
