## Calculate flour amount in starter

I'm trying to calculate the amount of flour (and water) in a certain number of grams of starter. The hydration is at 60%. I know that in 160 grams of starter, there are 100 g of flour and 60 of water, but what if I have a smaller or larger amount of starter in my recipe?

Here's the calculation

F= amount of flour

T = Total weight of starter

H=Hydration percentage

(F*H)=amount of water

T=F+(F*H)

T is known

H is known

I'm trying to solve for F and thereby find W (Water amount)

I just want to say that this website has been tremendously helpful, both in information and moral support. I'm baking loaves these days that I'm very pleased with and am now trying to "tweak" my formulas on a spreadsheet for timing and adjusting overall hydration.

thanks
