This converter allows you to convert megameters [Mm] to astronomical units [au] or astronomical units [au] to megameters [Mm]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.
Convert megameters to astronomical units
There are two simple ways to convert megameters [Mm] to astronomical units [au]. In the first calculation method, the value in megameters [Mm] is divided by 149,597.8707. The second method multiplies the value in megameters [Mm] by the rounded conversion factor of 6.685 * 10-6.
- Astronomical units [au] = megameters [Mm] ÷ 149,597.8707
- Astronomical units [au] ≈ megameters [Mm] * 6.685 * 10-6
The calculation method with a rounded conversion value is more suitable for rough conversions from megameters [Mm] to astronomical units [au], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.
Convert astronomical units to megameters
Converting astronomical units [au] to megameters [Mm] is easy and can be done in two ways. The first method involves multiplication, whereby the value in astronomical units [au] is multiplied by 149,597.8707. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 6.685 * 10-6.
- Megameters [Mm] = astronomical units [au] * 149,597.8707
- Megameters [Mm] ≈ astronomical units [au] ÷ (6.685 * 10-6)
The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from astronomical units [au] to megameters [Mm] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
