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:

11. Deci (d) = (10^{-1}) or 0.1
12. Centi (c) = (10^{-2}) or 0.01
13. Milli (m) = (10^{-3}) or 0.001
14. Micro (μ) = (10^{-6}) or 0.000001
15. Nano (n) = (10^{-9}) or 0.000000001
16. Pico (p) = (10^{-12}) or 0.000000000001
17. Femto (f) = (10^{-15}) or 0.000000000000001
18. Atto (a) = (10^{-18}) or 0.000000000000000001
19. Zepto (z) = (10^{-21}) or 0.000000000000000000001
20. 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.
