In the United States, where the old wine-gallon of 231 cubic inches is retained, the old wine-pint of 16 fluid ounces is used. 231 c.i. × 252·458 (grains of water in 1 c.i.) gives—
| 58,317·8 | grains | for | the | gallon |
| 7,289·7 | „ | „ | „ | pint |
| 455·6 | „ | „ | „ | ounce |
The fluid ounce is divided as in England into 8 fluid drachms, of 60 minims.

[28]. Curiously Lancashire still uses the Cheshire acre, and in some parts a pound of butter is a pound + the weight of 2 pennies, formerly the heavy Georgian ounce-pennies, now the lighter bronze coins.
