For my own memory. A variation of Archimedes' method for digital scales.
Нужен стаканчик с водой. Взвешиваем сначала объект, потом стаканчик с водой. Потом подвесив объект на нитке, опускаем его в воду, чтобы он ни с чем не соприкасался (держим нитку в руке). Плотность воды с достаточной точностью единица, так что:
Density = weight of object / (weight of beaker with water and object - weight of beaker with water)
