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).

Arab (Indian) (arab)
One hundred crore (10⁹), the same as a short-scale billion. Used in the South Asian number system.
Western numbers are named in steps of a thousand, with a new word at each third power of ten: thousand, million, billion. The Indian system adds a new word at every second power instead, giving lakh for 100,000, crore for 10 million, arab for 1,000 million and kharab for 100,000 million. An arab is a hundred crore, or 10 to the ninth power.
That equals the short-scale billion, so the two words name the same quantity, which sometimes causes confusion between Indian and international usage. Digits are grouped to match: the first three from the right are one group, and then pairs follow, so an arab is written 1,00,00,00,000 rather than 1,000,000,000.
The system is official and preferred in India, Pakistan and Bangladesh, and Indian English publications use lakh and crore for rupee amounts. Nepal and Sri Lanka used it in the past but have moved to the international system, and the Maldives still uses lakh in speech. Sanskrit mathematicians such as Shridhara named large numbers beyond koti in several incompatible ways, so older texts do not always give the same value.
1 arab (Indian) = 1,000,000,000 pieces (exactly).
