VKİ hesaplayıcı nasıl kullanılır

  1. Choose metric units (centimeters and kilograms) or convert your measurements first.
  2. Enter your height carefully. Small height errors change BMI more than small weight errors.
  3. Enter your current weight. Use a recent measurement for the most useful result.
  4. Read the BMI value and category in the results panel. The explanation tells you what the number means in plain language.
  5. Optionally compare with a related tool such as the age calculator if you are tracking health metrics over time.

Formül ve yöntem

Body mass index (BMI) is a simple screening measure that relates weight to height. It does not directly measure body fat, but it is widely used because it is easy to calculate and compare.

For metric inputs, weight is in kilograms and height is in meters. If you enter height in centimeters, divide by 100 before squaring.

Standard adult categories used by many public-health organizations are: underweight (BMI under 18.5), normal (18.5–24.9), overweight (25–29.9), and obesity (30 or higher). Category cutoffs can differ for children and some clinical contexts.

BMI = weight (kg) ÷ [height (m)]²

Çözümlü örnek

Boy 170 cm, kilo 68 kg → boy 1,70 m.

1,70² = 2,89; 68 ÷ 2,89 ≈ 23,5 → normal (18,5–24,9).

Aynı boyda 86 kg → ≈ 29,8 → fazla kilolu.

Sıkça sorulan sorular

VKİ nedir?

BMI (body mass index) is a height-to-weight ratio used as a quick screening tool. It is calculated as weight in kilograms divided by height in meters squared.

VKİ, sporcular veya yaşlı yetişkinler için doğru mu?

BMI does not distinguish muscle from fat. Muscular people may show a higher BMI without high body fat, and older adults may have different health implications at the same BMI. Treat BMI as a starting point, not a full health assessment.

Should children use the same BMI categories?

No. Children and teens need age- and sex-specific BMI percentiles. This page focuses on the standard adult calculation and categories.

Which units should I use?

The classic formula uses kilograms and meters. If you only know pounds and inches, convert first or use a unit mode when the interactive calculator supports it.

Does this tool give medical advice?

No. The BMI calculator is an educational estimate. Talk with a qualified clinician before making health decisions.

Why did my result change when I edited height?

Height is squared in the BMI formula, so small height changes affect the result more than the same relative change in weight.
