Actually most constants have been standardized to natural sources. A meter is now a fixed (small) fraction of the speed of light in vacuum. A second is pegged to the duration of a Cesium isotope spinning or something. Just that the multipliers are chosen to be convenient to us.
Should we need to talk measurements with aliens, we can, and can convert between their units and ours.
What’s more profound is that math is universal - after some teething pains with regards to understanding conventions, any alien technology should be comprehensive by us, and vice versa.
Well, akshually they started out as being earth specific, as convenient ways to measure human-relevant amounts of space and time, and were standardized after that. So really God still wouldn’t care to use meters or seconds, but would probably have their own units which could also be standardized with natural phenomena.
Right but the actual quantities are arbitrary. A metre is a fixed fraction of the speed of light in a vacuum, but it’s an arbitrary fraction chosen because it was convenient. We could just as well have chosen it to be half or twice as long. Same with the second. And the kilogram, etc.

Yeah in 2019 we even managed to get the pesky kilogram defined by a natural constant.
SI being capable of interspecies translation is an interesting thing I hadn’t considered.

“Wait you all started with base 60 and left it? It took us millenia to realize that it was the best choice, and once we did we never looked back”

What about imperial system?

IIRC it’s currently defined based on SI units.
An inch is just a special term for 2.54cm used by Americans (but not our government)
