How fast is the universe expanding in mph?

Answer 1

Owen Atkinson

152112 miles/h/megaparsec = 0.152112 mile/h/parsec= 3.063117 E-15 mile/h/mile.

The rate is currently equal to the Hubble constant.

#H_o#= 68 km/s/megaparsec

152112 miles/hour per megasecond

= 0.152112 kilometers per hour

E-07 miles/hour/AU = 7.374591

3.063117 E-15 miles per hour.

I've used i mile = 1.609344 km, 1 AU = 149597871 km, and 1 parsec = 206265 AU.

When converted to miles per hour (mph), the expansion rate of the universe is approximately 43.1 miles per second per million light-years (mi/s/Mly). This expansion rate is known as the Hubble constant, and it is currently estimated to be approximately 73.2 kilometers per second per megaparsec (km/s/Mpc).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
