I find when I am baking I am constantly converting recipes, and I always have to do all this math in my head. I finally came up with this baking conversion chart to help with the math and keep it simple. Print it out and keep it in your cookbooks or on your fridge!
This one is for teaspoons and tablespoons. My biggest pet peeve is when a recipe has 5 Tablespoons or 6 teaspoons. Just convert it already and then I don't have to count out all those little spoons.... sheeesh.
Always wondered how many cups were in a pint? This little chart will keep you in line and help you remember all those numbers. Remember: Water, milk, and eggs can be measured the same by weight and volume, saving you scaling you the time of scaling your eggs when all you need to do is put them in your measuring cup.
Here's a simple decimal/fraction chart. I find when I am trying to convert recipes at 5 am that sometimes these numbers escape my little mind. So this keeps me from making simple mistakes that take an hour to fix.
Hope this helps with your baking and kitchen math!
