Question 1

How do I calculate by BMI?

Accepted Answer

To calculate your BMI (Body Mass Index), divide your weight in kilograms by your height in meters squared: BMI = weight (kg) ÷ height (m)². For example, if you weigh 70 kg and are 1.75 m tall, your BMI is 70 ÷ (1.75 × 1.75) = 22.9. In imperial units, multiply your weight in pounds by 703, then divide by your height in inches squared. You can also use the free BMI calculator on CalculatorsDaily for instant, accurate results.

Question 2

What is a normal BMI?

Accepted Answer

According to the World Health Organization (WHO), a normal BMI for adults falls between 18.5 and 24.9. A BMI below 18.5 is classified as underweight, 25.0 to 29.9 is overweight, and 30.0 or above is considered obese. These BMI chart ranges apply equally to both men and women, though individual factors like muscle mass, age, and ethnicity can affect interpretation.

Question 3

What is the meaning of BMI calculator?

Accepted Answer

A BMI calculator is a digital tool that computes your Body Mass Index — a numerical value derived from your weight and height. BMI stands for Body Mass Index, and the calculator uses standard formulas (weight ÷ height²) endorsed by the WHO and CDC to classify your weight status as underweight, normal, overweight, or obese. It is a quick screening tool for health and weight evaluation.

Question 4

What is correct BMI for my age?

Accepted Answer

For adults aged 18 and older, the same normal BMI chart category (18.5–24.9) applies regardless of age. However, some geriatric researchers suggest a slightly higher range (23–27) may be healthier for adults over 65. For children and teens aged 2–17, BMI is evaluated using age- and sex-specific percentile charts rather than fixed numbers.

Question 5

How do I check my BMI at home?

Accepted Answer

To check your BMI at home: (1) Measure your height in meters or feet/inches. (2) Weigh yourself on a scale in kilograms or pounds. (3) Use the formula BMI = weight (kg) ÷ height (m)², or simply enter your measurements into the free CalculatorsDaily BMI calculator above for an instant result along with your BMI chart category and healthy weight range.

Question 6

What is 170 cm with 70 kg?

Accepted Answer

For a height of 170 cm and weight of 70 kg, the BMI calculation is: 70 ÷ (1.70 × 1.70) = 70 ÷ 2.89 = 24.2. A BMI of 24.2 falls within the 'Normal weight' category on the standard BMI chart (18.5–24.9). This is near the upper boundary of the healthy weight range (53.5–71.9 kg) for someone 170 cm tall.
