No 'B' Until Billion If you were to write out every number (one, two, three, etc.), you wouldn't use the letter "b" until you reached one billion. Grab paper and pen and start writing down every number as a word. If you spelled out every number, you would get to one billion before needing the second letter in the alphabet. 0-zero, 1-one, 2-two, 3-three, 4-four, 5-five, 6-six, 7-seven, 8-eight, 9-nine, 10-ten 11-eleven, 12-twelve, 13-thirteen, 14-fourteen, 15-fifteen, 16-sixteen, 17-seventeen, 18-eighteen, 19-nineteen, 20-twenty 21-twenty-one, 22-twenty-two, 23-twenty-three.........30-thirty 40-forty, 50-fifty, 60-sixty, 70-seventy, 80-eighty, 90-ninety, 100-one hundred 101-one hundred and one, 102-one hundred and two....... 999- nine hundred and ninety-nine 1,000-one thousand 1,000,000-one million 1,000,000,000-one (B)illion Stopping at one billion, all the letters used to form the numerical names would be A, B, __, D, E, F, G, H, I, __, __, L, M, N, O, __, __, R, S, T, U, V, W, X, Y, Z (and Z is only included for 0). Continuing onward, C occurs in octillion, P occurs in septillion, and Q is used in a quadrillion. No word J or K is ever used to construct numerical naming. After all, M as an initial letter to a numerical name doesn't get used until one million. The letter A (the first letter of the alphabet) doesn't get used in a numerical name until 101, one of the most commonly used letters in the English language. Source: ultimate facts
