What unit of measure does the Hubble constant use?

Answer 1

Lydia Allen

km/s/megaparsec

Currently, based on cutting-edge technological techniques in

measurements, the formula's Hubble constant,

Recession speed = #H_o# X distance,

#H_o#= 68 km/s/parsec, a little less than earlier estimates around 70. .

This indicates that a galaxy is moving away from us at a speed of 68 km/sec.

as each parsec is spaced.

The recession speed for N parsecs is equal to N km/s.

Here, one parsec equals 206265 AU and one megaparsec equals one million parsec.

30857 billion kilometers.

So, 1 megaparsec = 30857 million billion km = 3 X #10^19# km, nearly.. .

Kilometers per second per megaparsec (km/s/Mpc) is the unit of measurement used for the Hubble constant.

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.
