BMI for 100 kg and 182 cm
Instant answer: A person who weighs 100 kg (220 lbs) and is 182 cm (5'12") tall has a BMI of 30.2, classified as obese class i.
For an adult who is 182 cm tall, the World Health Organization considers a weight between 61.3 and 82.5 kg to be healthy.
What the numbers mean for you
You are 17.2 kg (38 lbs) above the healthy upper limit and 0.6 kg (1 lbs) above the obesity threshold.
A first, clinically meaningful goal is a 10% reduction — about 10.0 kg (22 lbs), achievable in roughly 22 weeks at a 500 kcal daily deficit. This alone typically improves blood pressure, HbA1c, and lipid profile.
Timelines assume ~7,700 kcal per kg of body fat. Real progress varies with muscle mass, adherence, and medications.
What does a BMI of 30.2 mean?
Cardiometabolic risk rises sharply in this band, but is far from deterministic — fitness, diet quality, and sleep substantially modify outcomes.
BMI is a screening tool, not a diagnosis. Two people at 100 kg and 182 cm can have very different body compositions and very different health profiles. Use BMI alongside waist circumference, fitness level, and routine bloodwork.
Waist matters more than the scale
Two people can share the same BMI and have very different metabolic risk. For that reason, waist circumference is now considered a stronger predictor of cardiometabolic disease than BMI alone.
- Waist-to-height rule: keep your waist under half your height — that means below 91 cm (36") at 182 cm.
- Absolute cutoff for most adults: waist under 94 cm (37") is associated with meaningfully lower risk of type 2 diabetes and cardiovascular disease.
- Higher-risk zone: waist above 102 cm (40") — this is where risk climbs sharply regardless of BMI.

Practical next steps
- Consult a GP for a full metabolic assessment (blood pressure, HbA1c, lipids).
- Set an initial target of 5–10% body-weight loss — clinically meaningful and achievable.
- Combine dietary change, daily movement, and sleep optimisation.
- Discuss whether structured programmes or medication are appropriate.
Frequently asked questions
What is the BMI for 100 kg and 182 cm?
Using the formula BMI = weight (kg) ÷ height (m)², a person who weighs 100 kg and is 182 cm tall has a BMI of 30.2. This places them in the obese class i category as defined by the World Health Organization.
Is 100 kg a healthy weight at 182 cm?
The healthy weight range for 182 cm is 61.3–82.5 kg, corresponding to a BMI of 18.5–24.9. 100 kg gives a BMI of 30.2, which is obese class i.
How was this BMI calculated?
BMI = 100 ÷ (1.82 × 1.82) = 100 ÷ 3.3124 = 30.2.
What should I do if my BMI is 30.2?
Consult a GP for a full metabolic assessment (blood pressure, HbA1c, lipids). Set an initial target of 5–10% body-weight loss — clinically meaningful and achievable.
