BMI for 175 cm and 100 kg
BMI = 32.7 (Obesity class I)
An adult who is 175 cm tall and weighs 100 kg has a body mass index of 32.7. The healthy weight range for this height (BMI 18.5–24.9) is about 56.7 kg to 76.3 kg.
For adults 20 and over. BMI is a screening measure, not a diagnosis.
How this BMI is calculated
- Height in meters: 1.75 m; squared: 3.062 m².
- BMI = weight ÷ height²: 100 ÷ 3.062 = 32.7.
BMI Prime (BMI ÷ 25) is 1.31: values above 1.0 are above the healthy range.
At this height, a weight of 76.3 kg or less corresponds to a BMI under 25.

BMI categories for adults (WHO)
- Under 18.5: underweight
- 18.5–24.9: healthy weight
- 25–29.9: overweight
- 30 or more: obesity (class I 30–34.9, II 35–39.9, III 40+)
For people of Asian descent, health risks rise at lower BMIs, and 23 and 27.5 are often used as action points. BMI does not separate muscle from fat, so very muscular people can have a high BMI without excess fat. It is a screening tool; talk to a health professional about your own situation.

Frequently asked questions
What is the BMI of someone 175 cm and 100 kg?
A BMI of 32.7, which the WHO classifies as Obesity class I for adults.
How is BMI calculated?
BMI is your weight in kilograms divided by your height in meters squared: BMI = kg ÷ m². In US units, BMI = 703 × pounds ÷ inches².
What is a healthy BMI?
For adults the World Health Organization classes 18.5 to 24.9 as a healthy weight, 25 to 29.9 as overweight and 30 or more as obesity. For people of Asian descent, lower cut-offs (23 and 27.5) are often used for health risk.
Is BMI accurate?
BMI is a quick screening measure, not a diagnosis. It does not distinguish muscle from fat, so it can overestimate fat in athletes and underestimate it in older adults. Waist size and other checks give a fuller picture.
