Conversion in SI Units

SI Unit Conversion Calculator

The International System of Units (SI Units) is provided by the Bureau International des Poids et Mesures (BIPM). SI is the modern form of the metric system, which contains e.g. weight indications in grams, milligrams and kilograms. It is used in The Review of Diabetic Studies. In some countries, among them the USA, partly other units are used. These are termed the conventional or US units.

Find below a chemical conversion table containing chemical compounds with factors for conversion from conventional to SI units as well as a calculator for conversions of all listed chemicals and substances. The calculation refers to the units indicated in the table. No responsibility is taken for the correctness of this information. The collection below includes glucose, which is also described in more detail here.

Recent changes: Insulin conversion factor from 6.945 to 6.0, hemoglobin from 0.6206 to 0.1551.

Calculator

Conversion:

Insert or select compound name (e.g. triglycerides) in the first field and value in the left hand field of the second or third section. Then click "yield" button for conversion into the wanted unit. Notice units indicated in the table (JAVA script must be activated).
