Hubble Law Distance Calculator

Find recession velocity from distance using Hubble's law.

Recession velocity (km/s) 7,000

Formula: v = H₀ · d

Step-by-step with your numbers:
1. Values used:
2. Distance = 100 Mpc
3. Hubble constant = 70 km/s/Mpc
4.
5. Recession velocity = Distance x Hubble constant = 100 x 70 = 7,000km/s
Did we solve your problem today?

Hubble's law says galaxies recede faster the farther away they are — evidence of cosmic expansion.

The math behind it

v = H₀·d, with H₀ ≈ 70 km/s per megaparsec.

Worked example

100 Mpc with H₀ = 70 → 7000 km/s.
