The prefixes provide an order of magnitude: Ex.
Name | Symbol | Value in SI Units |
---|---|---|
minute | min | 1 min = 60 s |
hour | h | 1 h = 60 min = 3600 s |
day | d | 1 d = 24 h = 86400 s |
degree | ° | 1° = (π/180) rad |
minute | ' | 1' = (1/60)° = (π/10800) rad |
second | '' | 1'' = (1/60)' = (π/648000) rad |
liter | l, L | 1 L = 1 dm 3 = 10 -3 m 3 |
metric ton | t | 1 t = 10 3 kg |
neper | Np | 1 Np = 1 |
bel | B | 1 B = (1/2) ln 10 Np |
nautical mile | 1 nautical mile = 1852 m | |
knot | knot | 1 knot = 1 nautical mile per hour = (1852/3600) m/s |
are | a | 1 a = 1 dam 2 = 10 2 m 2 |
hectare | ha | 1 ha = 1 hm 2 = 10 4 m 2 |
