mcgtomg.com is a unit converter for reference. Because it touches on medicines and supplements, please read where its limits are.

Not medical advice

The site converts numbers; it does not know your health, your medicine or your situation. Nothing here is medical, pharmaceutical or clinical advice, and it is not a prescription. For any actual dose, rely on your doctor, your pharmacist and the product label, not on this tool.

Doses depend on the label

The liquid-dose pages need a concentration, and the IU page needs the exact vitamin form. Those come from your specific product and can differ between brands, so read them off the packaging rather than assuming a typical value.

Lab results need context

The blood-test converter changes units only. It does not interpret a result; reference ranges vary by laboratory and person, so discuss any reading with a clinician.

The bottom line

We use standard factors and take care, but we can't promise a result fits your case, and we take no responsibility for decisions made on the strength of it. When in doubt, ask a professional.
