What prefix corresponds to 1,000,000,000,000 (one trillion)?

Explanation:
Understanding how SI prefixes map to powers of ten helps identify that 1,000,000,000,000 is 10^12. In this system, kilo stands for 10^3, mega for 10^6, giga for 10^9, and tera for 10^12. Since 10^12 equals one trillion, the corresponding prefix is tera. This sequence—kilo, mega, giga, tera—builds the scale by factors of a thousand, which makes tera the correct prefix for a trillion.
