Micrograms to Grams Converter
Using the Micrograms to Grams Converter
This converter allows you to find the equivalent values in micrograms to grams, or the other way around.
First, choose your input value (CONVERT FROM) as either grams (g) or micrograms (mcg).
The second step is to choose the output value (CONVERT TO) out of the same two units as before.
In case you are happy with the preselected units, you can skip the previous steps. Alternatively, if you want the exact opposite input and output value as the ones preselected, simply click on the icon with the two arrows.
Once everything is selected to your liking, fill in your input value as a decimal number and click on CONVERT.
You will receive a result in your output unit, rounded up to 16 decimal places.
You can also copy your result by clicking on the COPY icon next to it.
The very bottom part of the converter also shows the ratio between grams and micrograms (or the other way around, depending on your input and output selection). This ratio is the key to manually converting between the two units, as we will describe in the next section.
Converting between Micrograms and Grams Manually
The relationship between micrograms and grams is defined as 1 gram is equal to 1,000,000 micrograms.
Hence, the rate of grams to micrograms is 1:1,000,000.
The rate of micrograms to grams is 1:0.000,001.
This leads to two possible formulae:
mcg = g * 1,000,000
g = mcg * 0.000,001
Using these two formulae for manual conversions is fairly simple. The easiest way is to choose the one, where your output value is the subject of the formula. The two examples below will demonstrate this.
EXAMPLE 1: Convert 72.56 grams into micrograms.
Our output is in micrograms, hence we choose the first formula because it has the subject in mcg.
mcg = g * 1,000,000 \\= 72.56 * 1,000,000 \\= 72,560,000 ~mcg.
EXAMPLE 2: Convert 231,879 micrograms into grams.
Our output is in grams, hence we choose the second formula because the subject is in grams.
g = mcg * 0.000,001 \\= 231,879 * 0.000,001 \\= 0.231879 ~grams.
How small is a microgram
A microgram is an extremely small unit of measurement, where 1 microgram is equivalent to a gram split into a million equal parts.
To visualize this further, there are barely any substances that can be visible to the human eye if they are present in a mass of a couple of micrograms.
Some specific substances with extremely good light reflection properties can be observed in amounts of a couple of micrograms if placed on highly reflective surfaces in special conditions.
Most items in practical chemistry or medicine are measured in milligrams, so the question arises about what could be the practical application of micrograms.
The following list contains some common, everyday substances that are so effective, that their dosages are usually recommended in micrograms:
| Substance | Daily Dosage |
|---|---|
| Vitamin B | 30 to 400 micrograms |
| Vitamin A | ~600 micrograms |
| Vitamin D | ~5 micrograms |
| Iodine | ~150 micrograms |
| Selenium | ~35 micrograms |
Additionally, some powerful substances can be deadly for our bodies in doses as small as micrograms. Some examples are:
| Toxin | Usage |
|---|---|
| VX | An old poison that was often used by secret service agents around the world. For an average-sized human, the lethal dose is around 200 micrograms, which makes it an effective poison that can be hidden in drinks, food, or even tissues and items of clothing, without being recognized by the sense of taste or smell. |
| Botulinum toxin | The deadliest substance known to mankind at the moment. It is produced by anaerobic bacteria and is so effective, that a dose as little as 0.1 micrograms could kill an average-sized human, while a dose of 1 or 2 micrograms could take out a hippopotamus or an elephant |
