Default lactic acid on acid malt

My LHBS is out of acidulated malt and I need some. All I have right now is lactic acid. How much lactic acid in tsp or cc is in 1 lb of acid malt? I needed 2 lbs.

And do I put that amount into the mash or boil?

Based on googling, acid malt is about 3%, by weight, lactic acid. So, a pound would have 453.6 *.03 grams of pure lactic acid. The SG of 88% lactic acid solution is apparently about 1.21, so (453.6 *.03 / .88) * 1.21 ~= 18.711ml lactic acid (88% w/w)

Why do you need so much acid malt? Are you doing 20 gallon batches?
