To convert pm to meters: multiply by 10⁻¹². To convert pm to angstroms: divide by 100.
1 pm = 10⁻¹² m = 0.01 Å = 1,000 fm. One nanometer equals 1,000 picometers.
For example, 1 Picometer (pm) = 1.000000e-27 Petameter (Pm).
| Picometer (pm) | Petameter (Pm) |
|---|---|
| 0.1 | 1.000000e-28 |
| 0.5 | 5.000000e-28 |
| 1 | 1.000000e-27 |
| 2 | 2.000000e-27 |
| 5 | 5.000000e-27 |
| 10 | 1.000000e-26 |
| 25 | 2.500000e-26 |
| 50 | 5.000000e-26 |
| 100 | 1.000000e-25 |
| 500 | 5.000000e-25 |
| 1000 | 1.000000e-24 |
The picometer is a unit of length equal to 10⁻¹² meters, or one trillionth of a meter.
1 pm = 10⁻¹² m = 0.01 Å = 1,000 fm. One nanometer equals 1,000 picometers.
To convert pm to meters: multiply by 10⁻¹². To convert pm to angstroms: divide by 100.
Expressing covalent bond lengths (e.g., C–C bond ≈ 154 pm), atomic radii, and crystal lattice spacings.
The hydrogen atom has a radius of about 53 pm (the Bohr radius), while a carbon-carbon single bond is about 154 pm long.
Mixing up picometers and nanometers — remember 1 nm = 1,000 pm. Some sources still use the deprecated angstrom.
Think of pm as the natural unit for atoms: most atomic radii fall between 30 pm and 300 pm.
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.
