Livre (livre). The French livre is 500 g in modern use (the old livre was 489.5 g). Used in: Europe — France.
Microgram (µg). A microgram is one millionth of a gram, used for vitamins, medicines and trace amounts.
There are 500,000,000 micrograms in one livre.
Multiply the number of livres by 500,000,000. For example, 10 livres equal 5,000,000,000 micrograms.
One microgram equals 2 × 10⁻⁹ livres.
6,000,000,000 micrograms. Other common values: 5 livres = 2,500,000,000 micrograms and 100 livres = 50,000,000,000 micrograms.
