To convert Tm to AU: multiply by 6.685. To convert Tm to km: multiply by 10⁹.
1 Tm = 10¹² m = 10⁹ km = 6.685 AU.
For example, 1 Terameter (Tm) = 1436.080076 Sun's Radius (R☉).

The terameter is a unit of length equal to 10¹² meters, or one trillion meters (one billion kilometers).
1 Tm = 10¹² m = 10⁹ km = 6.685 AU.
To convert Tm to AU: multiply by 6.685. To convert Tm to km: multiply by 10⁹.
Expressing outer solar system distances in metric form, though AU is standard.
One light-hour is approximately 1.08 Tm. The distance to Pluto's orbit is roughly 5.9 Tm.
Confusing tera (10¹²) with other large prefixes. Remember: tera comes after giga in the SI scale.
Think of the outer solar system: Saturn is about 1.4 Tm from the Sun, a good mental anchor.
The solar radius is the radius of the Sun, approximately 6.9634 × 10⁸ meters (about 696,340 km).
1 R☉ = 6.9634 × 10⁸ m = 696,340 km ≈ 109 × Earth's radius ≈ 0.00465 AU.
To convert solar radii to km: multiply by 696,340. To convert solar radii to AU: multiply by 0.00465.
Describing stellar sizes: Betelgeuse ≈ 700 R☉, Sirius ≈ 1.7 R☉, a white dwarf ≈ 0.01 R☉.
You could line up about 109 Earths across the Sun's diameter. The largest known star (UY Scuti) is about 1,700 R☉.
Confusing solar radius with solar diameter — the diameter is 2 R☉. Also, stellar catalogs list radius, not diameter.
The Sun's radius (109 × Earth) gives a sense of scale: you could fit over a million Earths inside the Sun by volume.
