Black Hole Schwarzschild Radius Calculator

Calculate the Schwarzschild Radius

Enter the mass of the celestial body (e.g., in solar masses or kilograms).

Calculation Results

The Schwarzschild Radius (Rs) is:

This is the radius where the escape velocity equals the speed of light.

Unravel the mysteries of black holes! Our Black Hole Schwarzschild Radius Calculator helps you quickly determine the size of a black hole's event horizon based on its mass. Discover the critical radius where nothing, not even light, can escape, a fundamental concept in astrophysics.

Formula:

The Schwarzschild Radius (Rs) is calculated using the formula:
Rs = 2GM/c2
Where:

  • Rs = Schwarzschild Radius (meters)
  • G = Gravitational Constant (6.67430 × 10-11 N⋅m²/kg²)
  • M = Mass of the object (kilograms)
  • c = Speed of Light (299,792,458 m/s)
