The prefix ladder
Rungs from top to bottom
- M, mega: 106
- k, kilo: 103
- Base unit (m, g or L): 100
- c, centi: 10−2
- m, milli: 10−3
- μ, micro: 10−6
- n, nano: 10−9
Moving the decimal point
- The number of places between two rungs is the difference of their exponents. Kilo to centi is 3 − (−2) = 5 places.
- Down the ladder to a smaller unit, move the decimal point right. Smaller unit, bigger number: 1.5 km = 1500 m.
- Up the ladder to a larger unit, move it left: 325 mg = 0.325 g.
- Keep the zeros at the end, so the significant figures stay the same: 25.0 mL = 0.0250 L.
- Capital M is mega; lowercase m is milli. μ is the Greek letter mu.
