BMI calculator
Health Canada categories for adults 18+: under 18.5 underweight, 18.5–24.9 normal, 25–29.9 overweight, 30+ obese. BMI doesn't account for muscle, age, ethnicity or pregnancy; waist size adds useful context.
A1C to average blood sugar
ADAG formula. Diabetes Canada uses 6.0–6.4% for prediabetes and 6.5%+ for diabetes; most adults with diabetes aim for 7.0% or less. Your care team sets your personal target.
Blood sugar unit converter
