A black hole is a region of spacetime where gravity is so strong that nothing is capable of possessing enough energy to escape it. It is a true marvel in space as it has so many unanswered questions relating to them that scientists are still hard at work on figuring out. Despite our lack of knowledge, we do know a lot of different things about them. Calculating their temperature is among the short list of things we know about black holes.

How to Calculate the Temperature of a Black Hole

The formula for finding out the temperature of a black hole is:

Where:

T = Temperature of the black hole in Kelvins (K)

ħ (h-bar) = Reduced Planck's constant (approximately 1.0545718 × 10^-34 Joule seconds)

c = Speed of light in vacuum (approximately 2.998 × 10⁸ meters per second)

G = Gravitational constant (approximately 6.67430 × 10^-11 m³ kg^-1 s^-2)

M = Mass of the black hole in kilograms (kg)

k_B = Boltzmann constant (approximately 1.380649 × 10^-23 Joules per Kelvin)

Understanding Your Results

Your result will be displayed as a single temperature that is by default in Fahrenheit. This value will be the approximate temperature of the black hole in question. Our tool employs the most common and well-understood formula for calculating its temperature.

How to Use the Black Hole Temperature Tool

Our black hole temperature calculator tool is very simple and easy to use. The steps involved with using it include:

Enter the mass of the black hole.

Edit the unit used to define the mass if suns is not the best one.

Hit calculate and get your result!

Example Calculation

Let's say we find a new black hole that formed recently, we want to calculate what temperature it is. We already know its mass is about .0005 compared to Earth's mass. We can use this tool to get the temperature, first we will enter the mass which is .0005 then we will change the unit from suns to Earths.

Now we can hit calculate and find the black hole's temperature to be about -385.705 degrees Fahrenheit, or 41.092 kelvin.

Black Holes - Frequently Asked Questions

The quantum particles in a black hole are "fuzzy" due to the makeup of the structure, thus, energy cannot be bound by a black hole's event horizon. This makes black holes essentially absolute zero.

No, there is nothing that can survive a black hole.

Considering our limited understanding of black holes, we cannot say for sure. But it is currently believed that time does indeed stop inside of black holes.
