The wheel of SI prefixes
Spin this educational wheel and land on any SI prefix from the massive qu¹³⁰ (quetta) to the minuscule 10⁻³⁶ (just for fun!) — perfect for adding a measurement-twist to games, quizzes, or science challenges.
💡 Fun Fact: In November 2022, the SI system officially added the prefixes ronna (R, 10²⁷) and quetta (Q, 10³⁰), as well as their tiny counterparts ronto- and quecto- for 10⁻²⁷ and 10⁻³⁰.
