Bigger Than the Entire Universe: Why 1 Trillion to the 10Th Power Melts Modern Calculators
By Elena Rostova
Unpacking the actual math behind this calculation requires basic exponential arithmetic. The confusion online typically stems from differing naming conventions between English-speaking nations and regions relying on older numerical systems.
Under the short scale numeration system used in the United States and international finance, one trillion equals:
$$1,000,000,000,000 = 10^{12}$$
When raising an exponential expression to another power, standard exponentiation rules dictate that you multiply the powers together:
$$(10^{12})^{10} = 10^{12 \times 10} = 10^{120}$$
The end result is an integer written as 1 followed by 120 zeros:
`1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000`
Naming a number of this magnitude presents its own linguistic hurdles. Under modern short-scale naming rules, $10^{120}$ is officially named one noventrigintillion. In older British long-scale traditions or historical nomenclature tables, amateur mathematicians frequently mislabel or conflate it with names like novemvigintillion (which represents $10^{90}$ in the short scale or $10^{174}$ in classic Chuquet systems). To bypass linguistic tangles, physicists and computational scientists almost exclusively rely on scientific notation: $1 \times 10^{120}$.
