Hubble's Law Calculator
Hubble's Law
v = H₀ × d
What is the Hubble's Law Calculator?
Hubble's Law Calculator calculate recession velocity: v = h₀ × d. It is part of Home of Calculators's Astronomy Calculators suite for orbital mechanics, stellar properties, and cosmological calculations. The calculator is designed for astronomers, students, space enthusiasts, but anyone can use it. No signup, no ads, no tracking. Just accurate math, computed locally in your browser using a BigNumber-precision math engine.
Hubble's Law describes the expansion of the universe: galaxies are moving away from us at a velocity proportional to their distance. H₀ (Hubble constant) ≈ 70 km/s/Mpc. This was the first observational evidence of cosmic expansion.
H₀Hubble constant (~70 km/s/Mpc)dDistance (Mpc)How to use the Hubble's Law Calculator
- 1
Determine the distance
Find the distance to the galaxy in megaparsecs (Mpc).
- 2
Multiply by Hubble constant
Velocity = 70 × distance. The result is in km/s.
