How to Convert Terameter to Bohr Radius
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) = 1.889726e+22 Bohr Radius (a₀).

About Terameter (Tm)
Definition
The terameter is a unit of length equal to 10¹² meters, or one trillion meters (one billion kilometers).
Mathematical Relationship
1 Tm = 10¹² m = 10⁹ km = 6.685 AU.
Conversion Formula
To convert Tm to AU: multiply by 6.685. To convert Tm to km: multiply by 10⁹.
Practical Applications
Expressing outer solar system distances in metric form, though AU is standard.
Interesting Facts
One light-hour is approximately 1.08 Tm. The distance to Pluto's orbit is roughly 5.9 Tm.
Common Mistakes
Confusing tera (10¹²) with other large prefixes. Remember: tera comes after giga in the SI scale.
Educational Tips
Think of the outer solar system: Saturn is about 1.4 Tm from the Sun, a good mental anchor.
About Bohr Radius (a₀)
Definition
The Bohr radius is the most probable distance between the nucleus and the electron in a ground-state hydrogen atom, approximately 5.292 × 10⁻¹¹ meters.
Mathematical Relationship
a₀ = ℏ/(mec α) = 4πε₀ℏ²/(mee²) ≈ 5.29177 × 10⁻¹¹ m, where α is the fine-structure constant.
Conversion Formula
To convert Bohr radii to meters: multiply by 5.29177210903 × 10⁻¹¹.
Practical Applications
Sets the characteristic scale for atomic sizes. Most atoms have radii of 1–3 Bohr radii.
Interesting Facts
The Bohr radius gives atoms their characteristic size of ~1 Å (10⁻¹⁰ m), explaining why matter has the volume it does.
Common Mistakes
Confusing Bohr radius with atomic radius — the Bohr radius is specific to hydrogen; other atoms have different sizes.
Educational Tips
The Bohr radius tells you 'how big atoms are' — about 0.5 angstroms. It's the atomic analog of a ruler for atomic-scale physics.
