Mass Converter to Milligrams (mg)
High-precision converter for micrograms, carats, and grains to milligrams. Designed for chemistry, pharmacology, and gemology.
About
In fields like pharmacology and gemology, decimal placement errors can have severe consequences. Converting dosage units from Micrograms (mcg or μg) to Milligrams (mg) requires strict attention to the factor of 1000. A misunderstanding here can lead to a 1000-fold overdose or underdose.
Similarly, the jewelry trade relies on the Carat. One ct equals exactly 200 mg. This tool is designed with high-contrast typography and strict numeric validation to minimize reading errors when handling sensitive data from lab reports or inventory spreadsheets.

Formulas
The conversion logic is linear but deals with widely varying magnitudes.
mmg = minput × k
{
k = 1000 if unit is gk = 0.001 if unit is mcgk = 200 if unit is ct

Frequently Asked Questions
mg stands for Milligram (1/1000 of a gram). mcg stands for Microgram (1/1,000,000 of a gram). Therefore, 1000 mcg = 1 mg.
While the math is accurate, you should NEVER rely solely on an online calculator for clinical administration. Always cross-check with official formularies or a second professional.
Multiply the carat weight by 200. For example, a 0.5 ct diamond weighs exactly 100 mg.
To prevent parsing errors (e.g., European use of commas as decimals vs US use as separators), the tool cleans input to ensure only raw numeric data is processed.
