Research papers often report doses per kilogram of body weight, such as 3 mg/kg. A mg/kg dose converter turns that into a total amount for a specific weight, so you can read a study next to a product label.

This is a way to read research, not a dose recommendation.

How the math works

Total amount = dose per kg × body weight in kg

A study that gave 3 mg/kg to people weighing 70 kg gave each of them 210 mg. If your weight is in pounds, divide by 2.2046 to get kilograms.

Why a study's number is not your number

Participants, product forms, and conditions differ from one study to the next. A dose that worked in a trial is not an instruction for anyone else.

The NIH Office of Dietary Supplements notes that a health care provider may decide a different amount is more appropriate for you than a label suggests. That applies to study doses too.

Animal studies are a different case

A mg/kg figure from a mouse or rat study cannot be turned into a human amount with this converter. Animals absorb and clear substances differently, so the numbers do not carry over.

Compare it with a real product

With a total in hand, Study Dose vs Product Dose checks it against what a product delivers. For creatine, which is often dosed by weight, the Creatine Dosage Calculator does the work for you, and the Serving Size Converter helps when units do not match.

Pound to kilogram conversion follows NIST Handbook 44, Appendix C: General Tables of Units of Measurement, which defines the pound as 0.45359237 kg.
