That mpc is what's known as a megaparsec, roughly 3,260,000 light years.

If we now calculate the speed of the 1a supernovae from their color shift and correlate this with their distance, we arrive at a different value for the Hubble-Lemaitre constant -- namely just under 264,000 kilometers per hour per megaparsec distance.

Because Ho’oleilana is bigger than most baryon acoustic oscillations, the researchers think it could be a sign the universe is expanding at a faster rate than first thought — at roughly 76.9 kilometers per second per megaparsec, as opposed to the standard range of 67 to 74.

The universe is still expanding, at a rate of 73 kilometers per second per megaparsec, a metric known as Hubble's constant.

In their analysis, H0 comes out to be 73.04 ± 1.04 kilometers per second per megaparsec.
