About this conversion

The millimeter (mm) is a unit of length in the metric (SI), commonly used for engineering and manufacturing tolerances and bolt and screw dimensions. The astronomical unit (au) belongs to the astronomical and is typically found in measurements related to distances between planets and orbital radius of planets. By definition, one millimeter is one thousandth of a meter (0.001 m). One astronomical unit is approximately 149,597,870.7 km — the mean distance from Earth to the Sun. The conversion factor between these two units is 6.684587122268446e-15: multiplying any value in mm by this number gives the equivalent in au. For example, 10 mm equals 0.0000 au. Going the other direction, 1 au equals 149597870700000 mm.
