What is being measured?
Magnetic flux density and magnetic field strength are different quantities. Relating them can require a material model, not only a conversion factor.
This quantity is B, not magnetic field strength H. H-to-B requires permeability and material context.
Meaning of pT
Picoteslas uses the symbol pT in this library and measures magnetic flux density. Under the stated reference convention, 1 pT = approximately 1e-12 T. This equivalence changes how a known value is written. It does not increase measurement accuracy or establish whether a measurement is appropriate to a real application.
Conversion method
Multiply the value by the source factor (1e-12), then divide by the target factor (1). The factor ratio expresses the same magnetic flux density measurement in the other unit.
Worked example
For a known value of 10 pT, the reference conversion gives 1e-11 T. Converting that result back gives approximately 10 pT. This reverse check helps catch a reversed factor, but matching round-trip arithmetic alone does not independently verify a source definition.
Common reference values
| Input (pT) | Reference equivalent (T) |
|---|---|
| 1 | 1e-12 |
| 5 | 5e-12 |
| 10 | 1e-11 |
| 25 | 2.5e-11 |
| 50 | 5e-11 |
| 100 | 1e-10 |

| Gauss (G) | 1e-8 | Read definition |
| Milligauss (mG) | 0.00001 | Read definition |
Precision and common mistakes
- Keep the source and target quantity consistent. A matching symbol is not enough to establish a compatible definition.
- Record the original measurement precision. Showing twelve significant digits in a table does not make a rounded input more precise.
- Check symbol capitalization, prefixes and any regional convention in the source. Use the displayed unit definition rather than a similarly named unit.
- Factors involving repeating fractions or π use finite numerical precision. Round the final answer to the precision justified by your input.
