Formula: Converted = (Input x From Unit Count) / To Unit Count
Worked example โ 5 gross = 720 units = 60 dozen = 36 scores
Converted = (Input x From Unit Count) / To Unit Count
Each quantity unit represents a fixed number of individual items: pair = 2, half dozen = 6, dozen = 12, bakers dozen = 13, score = 20, gross = 144, great gross = 1,728, ream = 500. Convert by multiplying the input by its unit count, then dividing by the target unit count.
Problem:A manufacturer ships 5 gross of buttons. How many dozens and individual units is that?
Solution:Units = gross x 144 Units = 5 x 144 = 720 units Dozens = 720 / 12 = 60 dozen Scores = 720 / 20 = 36 scores
Result:5 gross = 720 units = 60 dozen = 36 scores
Problem:A store has 30 dozen eggs. Convert to gross, scores, and pairs.
Solution:Units = 30 x 12 = 360 Gross = 360 / 144 = 2.5 gross Scores = 360 / 20 = 18 scores Pairs = 360 / 2 = 180 pairs
Result:30 dozen = 360 units = 2.5 gross = 18 scores
A standard dozen is 12 items while a bakers dozen is 13. The bakers dozen originated in medieval England where bakers faced severe penalties including fines and flogging for shortchanging customers. To avoid any risk of being accused of selling underweight bread, bakers would include a 13th loaf with every dozen sold as insurance. This practice became so common it was codified into trade custom. The extra item is sometimes called the vantage loaf or the in-bread.
