Methanol Calculator

Use this calculator to find the amount of methanol neded in your biodiesel reaction

Select a standard biodiesel feedstock or enter the average molecular weight of your feedstock directly or Use Molecular weight calculator if you have a non standard feedstock


Triglyceride (oil or fat) feedstock 

Average molecular weight of the feedstock = You may also direcly input the molecular weight

Excess methanol used in reaction   %


Amount of methanol required per kg of oill = kg of methanol

Amount of methanol required per pound of oil = lbs of methanol

Amount of methanol required per gallon of oil = gal of methanol*

* Methanol volume is based on the assumption that specific gravity of oil is 0.91. If you have exact specific gravity of the oil, enter here and hit recalculate button.
