Unit Conversions and Prefixes

Seven Base SI Units (International System of Units)

m (meter) - length

kg (kilogram) - mass

s (seconds) - time

A (ampere) - electric current

K (kelvin) - temperature

cd (candela) - luminous intensity

mol (mole) - amount of substance

Length SI Unit

Meter (m)

Mass SI Unit

Kilogram (kg)

Time SI Unit

Seconds (s)

Electric Current SI Unit

Ampere (A)

Celsius to Kelvin conversion

^oC = K - 273

Kelvin to Celsius conversion

K = ^oC + 273

Fahrenheit to Celsius conversion

F = (9/5 x C) + 32

Celsius to Fahrenheit conversion

C = (5/9)(F - 32)
