Order these units from smallest to largest:

cm, um, km, mm, m, nm, dm, pm

Give each a measurement in terms of meters.

The units are ordered smallest to largest from top to bottom:

Picometer (pm) = 1 x 10⁻¹² meters

Nanometer (nm) = 1 x 10⁻⁹ meters

Micrometer (um) = 1 x 10⁻⁶ meters

Millimeter (mm) = 1 x 10⁻³ meters

Centimeter (cm) = 1 x 10⁻² meters

Decimeter (dm) = 1 x 10⁻¹ meters

Meters (m) = 1 meter

Kilometers (Km) = 1 x 10³ meters
