This converter allows you to convert astronomical units [au] to light minutes [lm] or light minutes [lm] to astronomical units [au]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 astronomical unit [au] ≈ 8.3167 light minutes [lm]1 light minute [lm] ≈ 0.1202 astronomical units [au]

Convert astronomical units to light minutes

There are two simple ways to convert astronomical units [au] to light minutes [lm]. In the first calculation method, the value in astronomical units [au] is divided by the rounded conversion factor of 0.1202. The second method multiplies the value in astronomical units [au] by the rounded conversion factor of 8.3167.

  • Light minutes [lm] ≈ astronomical units [au] ÷ 0.1202
  • Light minutes [lm] ≈ astronomical units [au] * 8.3167

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of astronomical units [au] to light minutes [lm] can be achieved using the following calculation method.

  • Light minutes [lm] = astronomical units [au] ÷ 15,330 ÷ 11,733.56 * 23,367 * 64,021

Convert light minutes to astronomical units

Converting light minutes [lm] to astronomical units [au] is easy and can be done in two ways. The first method involves multiplication, in which the value in light minutes [lm] is multiplied by the rounded conversion factor of 0.1202. The second variant is a division. Here, the value in light minutes [lm] is divided by the rounded conversion factor of 8.3167.

  • Astronomical units [au] ≈ light minutes [lm] * 0.1202
  • Astronomical units [au] ≈ light minutes [lm] ÷ 8.3167

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of light minutes [lm] to astronomical units [au] can be achieved using the following calculation method.

  • Astronomical units [au] = light minutes [lm] * 15,330 * 11,733.56 ÷ 23,367 ÷ 64,021
