Count Converter (Each, Dozen, Gross)

By Suraj GiriUpdated 24 September 2026

This page converts a count from one unit into another. Every value passes through the each, the SI unit count is held in, and count stays count: a unit only converts inside its own dimension.

How do you convert a count between each, dozens and gross?

Pick the unit you have, pick the unit you want, and type the value. The page multiplies by the factor between the two and prints the arithmetic under the result, so the answer and the working are the same object.

1. Choose the unit your value is in. This page opens on the gross.
2. Choose the unit you want it in. This page opens on the each.
3. Type the value, or the value with its units, such as 3 gr to ea. The result and the factor behind it appear together.
4. Read the working. It converts into the each first and out again, which is the same two lines you would write by hand.

Each, dozen and gross count items rather than measure them, so for a weight, length or volume, pick that quantity on the online unit converter.

Where These Factors Come From

Every factor above is read from the knowledge base rather than typed for the page, and every result is worked from those factors. These are the statements it holds for count.

• Count units are exact whole numbers: a pair is 2, a dozen is 12, a score is 20, a gross is 144 (a dozen dozen) and a great gross is 1728.
• How this page reports a result result as a whole count where the factor divides exactly, otherwise as a decimal

Is a Gross Always 144?

A gross is a dozen dozen and a great gross is a dozen gross, and both have been fixed counts for centuries. What varies from trade to trade is what gets called one item, so the count is exact and the thing being counted is yours to name.

• A gross here is a count, a dozen dozen, not a gross weight or a gross price.

The rule behind this factor is the same for every unit - how a conversion factor works.
