Mass is independent of the earth's gravity; our weight is the result of the planet's attraction. At our level, mass and weight are equivalent.

At any rate: hook the strop on the scale, put the o-ring of the scale on your doorknob, pull taut, and look at the numbers.

You will have an "objective" measurement of tension. There might be other similar tools that can be used to measure tension in a medium.
Did this, but only once & it was with a freshly honed razor on a thin roo strop. IIRC it was approx. 0.5kg. I imagine a thicker heavier strop may require different tension to achieve similar tautness.
