Both the Torah and Gemarrah use math in various places, e.g. percentages (5ths (certain penalties); 10ths (ma'aser), etc.)
They also use many terms of measurements - e.g. shekel = 20 gerah; numerous measurements (efah, e.g.) for sacrifices, etc.
Is there a book that explains in brief terms what these measurements are, with translations to either U.S. or metric terms, as well as cross refs. to either verses or Talmud page, etc. where these terms are mentioned?
Hard-copy book preferred, but a web site will also suffice.
