One day a planckhead and a meterhead were flying around the moon in a Mini Minor which had been specially modified for use in space. The planckhead checked the mileage gauge ("odometer") and saw that they were going 56 miles a minute. Indeed by counting the number of MacDonalds they passed over in one minute he could deduce this since there is a MacDonalds every mile or so on the lunar surface and they were passing 56 of these delicious fast food outlets every minute.
The Planckhead wondered what the moon would weigh in its own gravity, on its own surface. "...If I take a chunk that is a trillionth of her mass and weigh it on her surface, her whole weight would be a trillion times that force. How many ocques would that be: her weight in *her own terms*..." Remember that the ocque is the 2.7 pound planckian force unit used by planckheads. Meterheads use the "newton" force unit which is about 1/12 of an ocque. The universe's native great force, that shapes spacetime and is how gravity works, is a power-of-ten multiple of one ocque.
Now the planckhead was thinking about these things and it suddenly occurred to him that to find the weight of the moon all he needed to do was SQUARE 56 TWICE. The units are so good that is all you need to do. 56 squaredsquared is ten million (10^7) quartic speed units, each of which is worth 10^15 ocques so the moon weighs 10^22 ocques.
"Hey man," the planckhead slowly drawled to the meterhead who was spaced out in the Mini's back seat, " the moon, man. It weighs 10^22 ocques in its own surface gravity."
