How to use the hubble time calculator
Estimate the age scale of the universe from the Hubble constant. Enter hubble constant in the field above; the hubble time are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “Hubble time”, “age of universe from Hubble constant”, “1 over H0”, “calculate hubble time”, “find hubble time”.
Formula
Variables
- H0 — Hubble constant (km/s/Mpc)
Worked example
With hubble constant = 70 km/s/Mpc, the calculator gives hubble time ≈ 13.96857 billion years; hubble time ≈ 1.3969 × 10¹⁰ years.
Frequently asked questions
What is the hubble time calculator used for?
Estimate the age scale of the universe from the Hubble constant. It helps with questions such as “Hubble time”, “age of universe from Hubble constant”, “1 over H0”.
What is the formula for the hubble time calculation?
Hubble time (billion years) = 977.8 / H0. Hubble time (years) = [Hubble time] × 1e9. Here H0 is hubble constant (km/s/Mpc).
What inputs do I need for the hubble time calculator?
You need hubble constant in km/s/Mpc. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the hubble time calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the hubble time result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
