How Many Zeros in a Trevigintillion?
A trevigintillion has 72 zeros: 1072. It is the digit 1 followed by 72 zeros, spanning 73 digits in total — the 23rd "-illion" after a million in the short-scale system used in the United States and modern British English. The name uses the Latin roots tre- (three) and viginti (twenty). Trevigintillion equals 1 vigintillion (1063) multiplied by 109 (one billion). In the long-scale system used in parts of Europe, a trevigintillion represents 10138 — nearly double the exponent. The number has gained some pop-culture recognition through the game Cookie Clicker, where in-game currencies reach the vigintillion and trevigintillion range. Related: Zeros in an octillion.

The number has 24 groups of three zeros, confirming 3 × 24 = 72 zeros. Using the standard formula — position 23 in the sequence gives 3 × 23 + 3 = 72 — arrives at the same answer. In scientific notation, 1072 captures all of that in two characters and an exponent.
| Name | Zeros | Scientific Notation |

| Trevigintillion | 72 | 1072 |
| Quattuorvigintillion | 75 | 1075 |
How Many Zeros in 100 Trevigintillion?
One hundred trevigintillion (1074) has 74 zeros. Multiplying by 100 raises the exponent by 2 — from 1072 to 1074. The full scaling table:
- 1 trevigintillion = 1072 — 72 zeros
- 10 trevigintillion = 1073 — 73 zeros
- 100 trevigintillion = 1074 — 74 zeros
- 1,000 trevigintillion = 1075 — 75 zeros (= one quattuorvigintillion)
The long-scale trevigintillion equals 10138 (138 zeros) — a number 1066 times larger than the short-scale version. That factor of difference is exactly one unvigintillion, illustrating how rapidly the two conventions diverge at higher positions in the naming sequence. Learn more about zeros in a trillion.
