About these units
Dozen (doz)
Twelve items. Eggs, rolls and many goods are still sold by the dozen.
Dozen entered English from Old French douzaine, a group of twelve, built from douze, which comes from Latin duodecim, plus a suffix that makes a collective. Twelve earned its popularity partly by dividing evenly: it splits into halves, thirds, quarters, and sixths, which helps when sharing goods. One suggestion is that the roughly dozen lunar months in a solar year made twelve one of the earliest groupings.
Even in a decimal age, dozens persist in commerce, often for foods such as eggs. Larger multiples extend the system by twelves: a gross is 12 dozen, or 144, and a great gross is 12 gross, or 1,728. The idiom six of one, half a dozen of the other uses the unit to say two options come to the same thing. Twelve also gave English the baker's dozen, which adds one more.
1 dozen = 12 pieces (exactly).

Ream (rm)
500 sheets of paper (20 quires), the standard retail package for printer paper. A short ream of 480 sheets survives for some specialty papers.
Ream comes from the Arabic rizmah, a bundle of paper, passing through Spanish resma and Old French reyme; the Moors introduced cotton papermaking to Spain. Its size has varied. The modern standard, 500 sheets or 20 quires of 25, is the ISO and DIN definition and what retail paper almost always means. A short ream of 480 sheets, 20 quires of 24, was formerly the British standard and survives for tissue, greaseproof, handmade, and blotting papers. J. S. Bach's Weimar manuscript paper was ordered by the 480-sheet ream.
Other versions include the 516-sheet printer's or perfect ream, the 504-sheet envelope-paper ream, and the 472-sheet mill ream for handmade paper, which was 18 quires of 24 good sheets plus two 20-sheet quires of damaged ones. In 1922 the UK set machine-made writing and printing paper at 500 sheets. ISO 4046-3:2002 defines a ream as a pack of 500 identical sheets and recommends another term, such as pack, for other counts.
1 ream = 500 pieces (exactly).
