For the same practical reasons that water is available and familiar to all
of us, it is a good standard for weight; which is the force exerted on
Earth's terra firma surface by water and other substances; due to gravity.

We've calibrated our weight-scales to a standard of 62.4# per cubic foot of
water, because that's [pure] water's weight at its maximum density; which
maximum density has been found to be quite consistent.

For the finer weights of materials and substances used in everyday commerce
it has been found convenient for all practical intents and purposes to
assume that 0.016 cubic foot of water weighs 16 ounces, or 1 lbf. An amount
close enough that empty weight-scales can be set to a reading of zero, and
give results to 0.999% acuracy which is sufficient for all but the most
meticulous scientific purposes.

Speaking of practiacal--sand is more practicle in the desert.

So what would someone in space use? Or on the surface of the sun?

Heh

For what?

WHO's doing what _there_?

Huh?

Don't ask me, you quoted the wrong person..

What would be used in space or on the surface on the sun to measure
weight for practical reasons...

More of a joking question, but...
