Mass Proportions

If your talking pounds and ounces

In grains of truth how right you are

For seven thousand make a pound

Measured weights avoirdupois

How heavy is the argument

Against the grain or set in stone

Fair and square a balanced share

Where loss of value maybe prone

Avoid perversion of conversion

On standard particles with mass

When demonstrated in a vacuum

With no effect from air or gas

Whatever your convenience

How you bag your sack of wool

Your universal lump in motion

Defines the gravity you pull
