aris grains in a Paris cube foot of water = 645511

English grains in a Paris cube foot of water = 529922

Paris grains in an English cube foot of water = 533247

English grains in an English cube foot of water = 437489.4

English grains in an English cube inch of water = 253.175

By an experiment of Picard with the measure and
weight of the Chatelet, the Paris cube foot of
water contains of Paris grains = 641326

By one of Du Hamel, made with great care = 641376

By Homberg = 641666

These show some uncertainty in measures or in weights; but the above
computation from Everard's experiment may be relied on, because the
comparison of the foot of England with that of France was made by the
joint labours of the Royal Society of London and the French Academy of
Sciences: It agrees likewise very nearly with the weight assigned by Mr
Lavoisier, 70 Paris pounds to the cubical foot of water.
