Hubble Law Distance Calculator

Find recession velocity from distance using Hubble's law.

Calculated Output

Recession velocity (km/s) 7,000

Formula: v = H₀ · d

Step-by-Step Breakdown

1. Values used:

2. Distance = 100 Mpc

3. Hubble constant = 70 km/s/Mpc

5. Recession velocity = Distance x Hubble constant = 100 x 70 = 7,000km/s

Did this calculator solve your problem today?

The math behind it

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

100 Mpc with H₀ = 70 → 7000 km/s.

What is a megaparsec?

About 3.26 million light-years.
