One trillion equals 1,000,000,000,000, which is a 1 followed by 12 zeros. In other words, it is 1 thousand billion, or 1 million millions. If you need it in other common scales:
- In scientific notation: 1 × 10^12
- In words: one trillion
If you want a quick sense of scale, one trillion dollars is roughly equivalent to the combined annual expenditures of many large governments or the annual GDP of mid-sized economies, depending on the country and year.
