The following tables in CSV format are an abbreviated version of the NIST
["Special Publication 811: NIST Guide to the SI" Appendix B.9](https://www.nist.gov/pml/special-publication-811/nist-guide-si-appendix-b-conversion-factors/nist-guide-si-appendix-b9).
They are converted to a more easily machine readable format and are used for
verifying conversion accuracy of units in the db.json file.
They have the following basic format:
| Convert From | Convert To | Multipy By | Supported |
| ------------ | ---------- | ---------- | --------------- |
| ft / s | m / s | 3.048e-01 | true |
Which means that (1 ft / s) approximately equals (3.048e-01 m / s). The last
row indicates if the conversion is supported by the units located in the
`unitdata/db.json` database file. Non obvious or confusing units may have a
full name included in parenthesis to avoid confusion. For example:
| Convert From | Convert To | Multipy By | Supported |
| ------------- | ---------- | ---------- | --------------- |
| Gal (Galileo) | \[c\]m / s^2 | 1.0 | false |
It is assumed that most people would easily confuse this unit with the more
common "Gallon". So special notation is helpful.
