`t = 1.0/H`

4.40811E+17

**Hubble Time** is simply the reciprocal of the Hubble Parameter expressed in time units.

**INSTRUCTIONS**: Enter the following:

- (
**H**) Hubble Parameter in units of (km/s)/Mpc

**Hubble Time (t):** The time is returned in seconds. However, this can be automatically converted to compatible units via the pull-down menu.

The formula for Hubble Time is:

t = 1 / H

where:

- t = Hubble Time
- H = Hubble Parameter
