Tissue-culture preparation depends on unit discipline. One gram equals 1,000 milligrams; one liter equals 1,000 milliliters; one milliliter equals 1,000 microliters. The numbers are simple, but a misplaced factor of 1,000 can make a preparation unusable.
Understand it
Write the unit beside every value.
Convert units before multiplying if the units are not compatible.
Use leading zeros for values less than one and avoid ambiguous trailing zeros.
Important boundary
Never copy a numeric value without its unit.
Try it
