We have looked into metric/imperial conversion and it’s not feasible. The problem is ounces. Fluid ounces and weight ounces are different and most recipes don’t specify “fl oz”. To make matters worse some things you would think are sold by fluid ounces are actually sold by weight, like chicken broth. Chicken broth commonly comes in 14 1/2 oz cans. The contents *weigh* 14 1/2 ounces. Other times, things like chicken broth *are* sold by volume, so there’s no way to guess correctly.
