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) = 0.001 Petameter (Pm).
| Terameter (Tm) | Petameter (Pm) |
|---|---|
| 0.1 | 0.0001 |
| 0.5 | 0.0005 |
| 1 | 0.001 |
| 2 | 0.002 |
| 5 | 0.005 |
| 10 | 0.01 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |
| 500 | 0.5 |
| 1000 | 1 |
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 petameter is a unit of length equal to 10¹⁵ meters, or about 0.1 light-years.
1 Pm = 10¹⁵ m ≈ 0.1057 light-years ≈ 0.0324 parsecs.
To convert Pm to light-years: divide by 9.461. To convert Pm to parsecs: divide by 30.857.
No practical everyday applications. Would describe distances to nearby stars in metric.
1 light-year ≈ 9.46 Pm. The Oort Cloud extends to roughly 15,000 Pm from the Sun.
Case sensitivity is critical: Pm (petameter) vs. pm (picometer) differ by a factor of 10²⁷!
Remember: 1 light-year ≈ 9.46 Pm, so a few Pm is a fraction of the distance to the nearest star.
