Counting II: Cardinal Numbers 101 to 1,000,000+

To form numbers in Spanish beyond 100, just choose from each column:

milcien/cientouno/a
dos mildoscientosdos
tres miltrescientostreintatres
cuatro mil      cuatrocientos      cuarentacuatro
cinco milquinientoscincuenta      cinco
seis milseiscientossesentay      seis
siete milsetecientossetentasiete
ocho milochocientosochentaocho
nueve milnovecientosnoventanueve
diez, once...
veintinueve

One thousand two hundred and thirty-four is mil doscientos treinta y cuatro.


Cien is used for one hundred. Ciento is used for numbers greater than one hundred: ciento uno, ciento dos, etc.


Note that one thousand is mil (without un).


Note, as well, that in Spanish the y (and) goes between the tens and the ones, NOT between the hundreds and tens as in English.

Ten/twenty... thousand is diez/veinte...  mil, and the same holds true for hundred thousand, etc.:

  • One hundred and twenty-three thousand, four hundred and fifty-six
    cientoveintitrés mil, cuantrocientoscincuenta y dos

Note that the English billion is mil millones in Spanish; un billón in Spanish means one trillion in English.


In most European countries, thousands numbers are written with a period (full stop) instead of a comma: 1.250 = 1,250 (one thousand, two hundred and fifty) and the comma is used instead of a period/full stop with decimals: 1,5 = 1.5 (one and five-tenths).
