how to convert mg/m2 to mg/kg
Forum rules
Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

Expand your abbreviations.
if you have 1000 milligrams, which is equal to 1 gram, spread over 1 square metre, what is it you want to convert?
You are asking for the number of milligrams per kilogram.
THat's just the same as trying to convert pounds (weight) per acre to pounds per ton. It doesn't make sense.

re: how to convert mg/m2 to mg/kg

I assume this is for drug dosages, where some are specified as mg/kg (related to body mass), while some are specified as mg/m2 (related to "body surface area" or BSA).
So you need to find someone's BSA. There are several formulas, all of which take into account height in addition to mass. One of the easiest is Mosteller's formula.
BSA (m²) = ( [Height(cm) x Weight(kg) ]/ 3600 )½
e.g. BSA = SQRT( (cm*kg)/3600 )
or in inches and pounds:
BSA (m²) = ( [Height(in) x Weight(lbs) ]/ 3131 )½
I'm 6' 0" tall (183 cm) and weigh 175 lbs (80 kg). My BSA is 2.02.
My wife is 5'4" tall (163 cm) and weighs 125 lbs (57 kg). Her BSA is 1.6.
For other formulas, try googling "body surface area".
Hope this helps.

how, what is calculation
