Micro is a Unit Prefix that means a number is 1000,000 times smaller than the normal unit.

Micro can be shortened to the greek letter µ (pronounced 'mew').

A micrometre (µm) is 1/1000,000th of a metre (m).

A microvolt (µV) is 1/1000,000th of a volt (V).

A microgram (µg) is 1/1000,000th of a gram (g).

A bacteria may be 1 micrometre (1µm) long.

A grain of salt may be 50 micrograms (50µg) in mass.

To convert from micro to the base unit you must divide by 1000,000. \[63000\mu m = \frac{63000}{1000,000}m = 0.063m\]

\[8400\mu m = \frac{8400}{1000,000}m = 0.0084m\]

\[260\mu m = \frac{260}{1000,000}m = 0.00026m\]

\[98\mu m = \frac{98}{1000,000}m = 0.000098m\]

\[3\mu m = \frac{3}{1000,000}m = 0.000003m\]

To convert to micro from a base unit you must times by 1000,000. \[8m = 8\times1000,000 \mu m = 8,000,000\mu m\]

\[54m = 54\times1000,000 \mu m = 24,000,000\mu m\]

\[6.2m = 6.2\times1000,000 \mu m = 6,200,000\mu m\]

\[0.33m = 0.33\times1000,000 \mu m = 330,000\mu m\]

\[0.052m = 0.052\times1000,000 \mu m = 52,000\mu m\]
