1 tera = how much?

Think it through first, then pick an option.

  1. a 10¹⁵
  2. b 10¹²
  3. c 10⁻¹²
  4. d 10⁻¹⁵
Answer and explanation

Correct answer: b 10¹²

Tera (T) = 10¹².

Why the other options are wrong

  • a 10¹⁵: 10¹⁵ is peta (P), a different prefix; tera is 10¹².
  • c 10⁻¹²: 10⁻¹² is pico (p), a different prefix; tera is 10¹².
  • d 10⁻¹⁵: 10⁻¹⁵ is femto (f), a different prefix; tera is 10¹².
