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 Math / Science
The formula for Hubble Time is:
t = 1 / H
where:
The units of the Hubble Parameter are kilometers per second per megaparsec (km/s)/Mpc.
One Mega-Parsec is approximately equal to:
- 30,856,770,000,000,000,000 kilometers
- 19,173,507,963,493,200,000 miles
- 206,264,767,389 astronomical units (ua)
- 3,261,632 light years
