A BMI of 70kg is not a valid statement; BMI (Body Mass Index) is a ratio calculated using weight and height, not a weight alone. Therefore, a specific height is needed to calculate the BMI for a weight of 70kg.
To calculate BMI, you divide weight in kilograms by height in meters squared:
BMI = weight (kg) / (height (m))^2
Here's how BMI changes for a 70kg individual at different heights:
BMI Examples for a 70kg Individual
| Height (m) | BMI | BMI Category |
|---|---|---|
| 1.50 | 31.1 | Obese |
| 1.60 | 27.3 | Overweight |
| 1.70 | 24.2 | Normal weight |
| 1.75 | 22.9 | Normal weight |
| 1.80 | 21.6 | Normal weight |
| 1.85 | 20.5 | Normal weight |
| 1.90 | 19.4 | Normal weight |
Explanation:
- Obese: BMI of 30 or higher.
- Overweight: BMI between 25 and 29.9.
- Normal Weight: BMI between 18.5 and 24.9.
In conclusion, stating "a BMI of 70kg" is incorrect. You need to specify a height along with the 70kg weight to calculate the BMI value.
