The International System of Units (SI) uses prefixes to denote decimal or power of ten multiples and submultiples of its base units. Here’s a list of common SI prefixes:

  1. Yotta (Y) = (10^{24}) or 1,000,000,000,000,000,000,000,000
  2. Zetta (Z) = (10^{21}) or 1,000,000,000,000,000,000,000
  3. Exa (E) = (10^{18}) or 1,000,000,000,000,000,000
  4. Peta (P) = (10^{15}) or 1,000,000,000,000,000
  5. Tera (T) = (10^{12}) or 1,000,000,000,000
  6. Giga (G) = (10^{9}) or 1,000,000,000
  7. Mega (M) = (10^{6}) or 1,000,000
  8. Kilo (k) = (10^{3}) or 1,000
  9. Hecto (h) = (10^{2}) or 100
  10. Deca (da) = (10^{1}) or 10

For values less than one:

  1. Deci (d) = (10^{-1}) or 0.1
  2. Centi (c) = (10^{-2}) or 0.01
  3. Milli (m) = (10^{-3}) or 0.001
  4. Micro (μ) = (10^{-6}) or 0.000001
  5. Nano (n) = (10^{-9}) or 0.000000001
  6. Pico (p) = (10^{-12}) or 0.000000000001
  7. Femto (f) = (10^{-15}) or 0.000000000000001
  8. Atto (a) = (10^{-18}) or 0.000000000000000001
  9. Zepto (z) = (10^{-21}) or 0.000000000000000000001
  10. Yocto (y) = (10^{-24}) or 0.000000000000000000000001

These prefixes help to simplify and standardize measurements, making it easier to compare and convert between different scales.
