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 the world-wide mostly applied system in technology and science and the preferred system of units used in The Review of Diabetic Studies. In some countries, among them the USA, partly other units are used. We call these the conventional or US units.
Find below a chemical conversion table containing chemical compounds with factors for conversion from conventional (or US) 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 .
