This converter allows you to convert terameters [Tm] to astronomical units [au] or astronomical units [au] to terameters [Tm]. 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 terameter [Tm] ≈ 6.6846 astronomical units [au]1 astronomical unit [au] ≈ 0.1496 terameters [Tm]

Convert terameters to astronomical units

There are two simple ways to convert terameters [Tm] to astronomical units [au]. In the first calculation method, the value in terameters [Tm] is divided by the rounded conversion factor of 0.1496. The second method multiplies the value in terameters [Tm] by the rounded conversion factor of 6.6846.

  • Astronomical units [au] ≈ terameters [Tm] ÷ 0.1496
  • Astronomical units [au] ≈ terameters [Tm] * 6.6846

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

  • Astronomical units [au] = terameters [Tm] ÷ 23,367 ÷ 64,021 * 1010

Convert astronomical units to terameters

Converting astronomical units [au] to terameters [Tm] 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 0.1496. The second variant is a division. Here, the value in astronomical units [au] is divided by the rounded conversion factor of 6.6846.

  • Terameters [Tm] ≈ astronomical units [au] * 0.1496
  • Terameters [Tm] ≈ astronomical units [au] ÷ 6.6846

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 terameters [Tm] can be achieved using the following calculation method.

  • Terameters [Tm] = astronomical units [au] * 23,367 * 64,021 ÷ 1010
