Rim, Gross (Paper measurement)
A Ream is the standard unit for wholesale paper. Historically, a printer's ream consisted of 480 sheets. While modern "commercial" reams are often 500 sheets, in traditional educational curriculum, 1 Ream = 480 sheets = 20 Quires.
Examples
Example 1
How many sheets are there in 2.5 Quires?
1 Quire = 24 sheets. So, 2.5 x 24 = 60.
Answer: 60 sheets
Tricks and Shortcuts
Always remember: Quire = 24 and Ream = 20 x 24. To convert Reams to Dozens, multiply by 40.

Confusing a Dozen (12) with a Quire (24). A Quire is exactly two dozens.
