# Bispirazole 250 mg corresponds to the number of grams

## How much is a milligram (mg)?

Milligram is a physical unit for the mass of a body. The unit symbol is mg. The Base unit for mass is one kilogram. A gram is a thousandth of a kilogram - a milligram is a thousandth of a gram.

It follows that a milligram is a millionth of a kilogram. The international prototype of the kilogram was created in 1889. The "original kilogram" is cylindrical and consists of platinum (90%) and iridium (10%). All other units of mass are derived from it.

### Convert Milligrams to ...

Convert milligrams into another volume:

A drop of water (e.g. on a leaf in the morning dew) can contain up to one milliliter and has a mass of around one gram (1000 milligrams).

In pharmacology there is a special "drop unit". For this calculation, a drop is much smaller than a water drop (only approx. 5%). Hence contains agtt Metric ("gutta") exactly 50 microliters (0.05 ml). So-called drop counters use exactly 20 drops for one milliliter when dispensing medication. As a historical unit of weight for pharmacists, one drop (blood) corresponds to around 0.05 grams or 50 milligrams.

### Example: hemoglobin in the blood

Hemoglobin is a component of red blood cells. Hemoglobin can bind oxygen and carbon dioxide and transport them through the body. Oxygen provides the cells with energy, so the hemoglobin concentration is very important. The mean corpuscular hemoglobin concentration (engl. mean corpuscular / cellular hemoglobin concentration, MCHC) denotes the average hemoglobin concentration of the hematocrit (the mass of erythrocytes). In healthy people, the normal values ​​are between 32 and 36 Grams per deciliter. That corresponds to the unit 'Milligrams per 100 microliters (µl)'. This range applies to both women and men. See also hemoglobin (blood level Hb).

### Units of measurement for mass / weights (table)

The unit of measurement for mass (colloquially also weight) is one kilogram. The starting point for the standardization was the French National Assembly, which from 1790 (shortly after the French Revolution) wanted to establish a uniform and standardized system of unity. The international kilogram prototype is a cylinder 39 millimeters high and 39 mm in diameter, made of an alloy of platinum (90%) and iridium (10%). All other weight units are derived from it:
