In my thought experiment I am standing at the beach on a cold winter's morning. There's frost on the grass. Pretty standard, really. I have some scales that are accurate to the nearest gram. I have some tungsten with a mass of 1000kg and same mass of berylium. I weigh them on the scales. Which weighs more? In my thought experiment they have different weights, and, if you add the difference (in kg) to both the lat and the long you will have the final co-ordinates :)
