Reference ranges for blood tests of plasma renin activity can be given both in mass and in international units (μIU/mL or equivalently mIU/L, improperly shown as μU/mL or U/L, confusing mcU/mL used where Greek μ not available), with the former being roughly convertible to the latter by multiplying with 11.2.

List of conversion factors. ... ≡ 1 ⁄ 12 mL ... 1 ⁄ 100 of the energy required to warm one gram of air-free water from 0 °C to 100 °C at a pressure of 1 atm
The normal range of GFR, adjusted for body surface area, is 100–130 average 125 mL/min/1.73m 2 in men and 90–120 ml/min/1.73m 2 in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 mL/min/1.73 m 2 until 2 years of age in both sexes, and then it progressively decreases.
Using the 2005 Conversion Factor of $37.90, Medicare paid 1.57 * $37.90 for each 99213 performed, or $59.50. Most specialties charge 200–400% of Medicare rates for their procedures and collect between 50 and 80% of those charges, after contractual adjustments and write-offs. [citation needed]
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...

The sum of the three geographically weighted RVU values is then multiplied by the Medicare conversion factor to obtain a final price. [1] Historically, a private group of 29 (mostly specialist ) physicians—the American Medical Association 's Specialty Society Relative Value Scale Update Committee (RUC)—have largely determined Medicare's RVU ...
For example, on a certain monitor, the horizontal distance between the upper limits for parathyroid hormone in pmol/L and pg/mL may be 7 cm, with the mass concentration to the right. A molar concentration of, for example, 5 pmol/L would therefore correspond to a mass concentration located 7 cm to the right in the mass diagram, that is ...
