# A micron is 1 times 10^-6 meter. How do you write that number and unit in standard form?

$1 \cdot \mu m = \frac{1}{1000000} \cdot m$
$1 \cdot \mu m = 1 \times {10}^{-} 6 \cdot m = \frac{1}{1000000} \cdot m = {10}^{-} 3 \times {10}^{-} 3 \cdot m = {10}^{-} 3 \cdot m m$
$1 \cdot \mu m \cong 0.000039 \cdot \text{inch}$,
Sometimes the symbol $\text{um}$ is used, if you cannot find the Greek symbol.
