Example 1
- 70 kg
- 170 cm
24.2
What BMI at 70 kg and 170 cm? 24.2. The same WHO quotient as the BMI card.
Body mass index
Type weight and height. 70 kg and 170 cm give 24.2. 92 kg and 180 cm give 28.4. 55 kg and 165 cm give 20.2. Same WHO BMI as the BMI card. BMR and TDEE only when you add age, sex, and activity.
Not a clinic verdict. The main result is BMI with one decimal place. BMR and TDEE do not run from the two fields alone.

How it works
Body mass index in this calculator is weight in kg divided by height in metres squared. 70 / 1.70² = 24.221. The calculator writes 24.2 in the result. 92 kg and 180 cm give 28.4. 55 kg and 165 cm give 20.2.
This is the same WHO formula as the BMI card. The 18.5, 25, 30, and 40 cuts sit in the script. The category label comes from an i18n key, not a second table. 24.2 alone does not need age.
Mifflin BMR and PAL TDEE show only when age, sex, and activity are filled. Without those fields you still get 24.2. The Deurenberg fat sketch also waits for age and sex.
The mass band at BMI 18.5 to 25 is an extra row. It does not overwrite 24.2. The BMI card next door has the same quotient without those extras.
Type weight, type height, then Calculate. A comma in 70.5 parses. Zero height leaves 0 and a dash. A sketch from a quotient, not a diagnosis.
70 kg and 170 cm give 24.2. 92 kg and 180 cm give 28.4. 55 kg and 165 cm give 20.2. With a US header, weight is pounds and height is inches.
Formula
BMI = weight[kg] / (height[m])²
How to use
- Type weight and height, for example 70 kg and 170 cm.
- Type height in cm, for example 170.
- Click Calculate. The result is 24.2.
- 92 kg and 180 cm give 28.4. 55 kg and 165 cm give 20.2.
- BMR and TDEE run here only after age, sex, and activity. Or on the BMR and TDEE cards.
70 kg and 170 cm = 24.2
BMI = kg / m². 70 and 170 give 24.2. BMR and TDEE only after age, sex, and activity.
- BMI
- The WHO quotient. 70 kg and 170 cm show 24.2. Not a Devine mass.
- WHO
- Cuts 18.5, 25, 30, and 40 in the script. 92 kg and 180 cm give 28.4.
- TDEE
- An option from Mifflin and PAL. 24.2 alone does not compute TDEE.

Common questions
What BMI at 70 kg and 170 cm?
24.2. 70 / 1.70², then one decimal place in the result.
What about 92 kg and 180 cm?
28.4. The same WHO quotient.
What about 55 kg and 165 cm?
20.2.
Is this a different formula from the BMI card?
No. The same kg / m² and the same WHO cuts. Extra rows are optional.
When does BMR show?
When you type age and sex. 24.2 alone does not need them.
When does TDEE show?
When BMR is ready and activity from the PAL list is set. No activity hides TDEE.
Is 24.2 a diagnosis?
No. A sketch from a quotient. Not a clinic verdict.
Does a comma in 70.5 work?
Yes. 70.5 and 70,5 are the same weight.
Does a US header change 70 and 170?
Yes. Then 70 is pounds and 170 is inches. The 24.2 examples are metric.
