Meaning
Micro is a Unit Prefix that means a number is 1000,000 times smaller than the normal unit.
About Micro
- Micro can be shortened to the greek letter µ (pronounced 'mew').
Examples
- 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).
Converting from Micro
To convert from micro to the base unit you must divide by 1000,000. \[63000\mu m = (63000/1000,000)m = 0.063m\] \[8400µm = (8400/1000,000)m = 0.0084m\] \[260µm = (260/1000,000)m = 0.00026m\] \[98µm = (98/1000,000)m = 0.000098m\] \[3µm = (3/1000,000)m = 0.000003m\]
Converting to Micro
To convert to micro from a base unit you must times by 1000,000. \[8m = 8x1000,000µm = 8,000,000µm\] \[54m = 54x1000,000µm = 24,000,000µm\] \[6.2m = 6.2x1000,000µm = 6,200,000µm\] \[0.33m = 0.33x1000,000µm = 330,000µm\] \[0.052m = 0.052x1000,000µm = 52,000µm\]
