Health calculators - estimates with explanations
Each calculator describes its method and limitations: BMI, daily calorie needs (Mifflin-St Jeor), blood alcohol content (Widmark formula), fertile days and ovulation, and pregnancy due date. Results are estimates and do not replace advice from a doctor or dietitian - and never a breathalyser test.
