This converter allows you to convert meters [m] to astronomical units [au] or astronomical units [au] to meters [m]. 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 meter [m] ≈ 6.685 * 10-12 astronomical units [au]1 astronomical unit [au] ≈ 1.496 * 1011 meters [m]

Convert meters to astronomical units

There are two simple ways to convert meters [m] to astronomical units [au]. In the first calculation method, the value in meters [m] is divided by the rounded conversion factor of 1.496 * 1011. The second method multiplies the value in meters [m] by the rounded conversion factor of 6.685 * 10-12.

  • Astronomical units [au] ≈ meters [m] ÷ (1.496 * 1011)
  • Astronomical units [au] ≈ meters [m] * 6.685 * 10-12

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

  • Astronomical units [au] = meters [m] ÷ 384,126 ÷ 389,450

Convert astronomical units to meters

Converting astronomical units [au] to meters [m] is easy and can be done in two ways. The first method involves multiplication, in which the value in astronomical units [au] is multiplied by the rounded conversion factor of 1.496 * 1011. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 6.685 * 10-12.

  • Meters [m] ≈ astronomical units [au] * 1.496 * 1011
  • Meters [m] ≈ astronomical units [au] ÷ (6.685 * 10-12)

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

  • Meters [m] = astronomical units [au] * 384,126 * 389,450

Speed

While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
