<!--
Guidelines:
1. write unit names in lower case
2. use only common abbreviations, leave blank if there is no abbriviation
3. for units that have different definitions i.e. "calorie" provide info about
conversion factor used for this unit.
4. use scientific notation for long conversion factors (more than 3 zeros),
i.e. 1e7 instead of 10000000
5. SI units are major units i.e. m, kg, s, Pa, ..., meaning their values are: lf=1 cf=0
6. Conversion factors of other units are relative to major units, i.e. y=lf*x+cf
where x is major unit value
7. Do not round conversion factors!!! use as many digits as you can
8. Compulsory attributes: name, lf
9. Optional attributes: abbr, cf, info
