Quandaries and Queries


 My son is doing an demonstration for science class about how to make biodiesel. we are having problems with the conversion. for instance we think there are approx 190 liters in 50 gallons. Is this correct? Also if you needed 3.5 grams of lye per liter, would that be 662g of lye.


Hi William,

I assume you want US gallons and one US gallon is 3.785 liters. Thus 50 US gallons is

50 3.785 = 189.25 lites.

You need 3.5 grams per liter so you need

189.25 3.5 = 662.375 grams of lye.
