# Coffee Ratio Calculator

I often have trouble with coffee ratios. Lately, I have been winging the amount of coffee I use in a brew so that I don't have to calculate how much coffee to use. This is suboptimal because it means that I'm probably not producing the sort of cup that I want. I know that I like to use 15 grams of coffee per 250 grams of water but I don't usually do any maths to figure out how much more coffee I need if I want to use more water. I just take a punt.

I decided to put together a calculator that gives me the ratio information I will need in my brewing. This calculator:

- Figures out the most simple version of a ratio
- Calculates how much water to use in a recipe, given a particular ratio and coffee dose.
- Calculates how much coffee to use in a recipe, given a particular ratio and water amount.
