Below are exact conversions to metric units of measure from U.S. units of measure. For the purposes of use in a professional kitchen, the metric measures in this book were rounded to the nearest 10 grams, with the exception of those ingredients such as leaveners where rounding would have an adverse effect on the finished product.
Exact measurement conversion was used for the following: small weight and volume ingredients (under ½ ounce), chemical and natural leaveners, salts, spices, herbs, flavored oils and fats, extract liquids, and all hydrocolloids.
