The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton.

What are the three formulas for density?

• To work out density: p = m / V.
• To work out the mass: m = p x V.
• To work out the volume: V = m / p.

The SI unit of mass is the kilogram (kg). Thus, the SI unit of the quantity weight defined in this way (force) is the newton (N).

So, “H/S = h/s.” For example, if s=1 meter, h=0.5 meter and S=20 meters, then H=10 meters, the height of the object.

For adults, a healthy weight is defined as the appropriate body weight in relation to height. This ratio of weight to height is known as the body mass index (BMI). People who are overweight (BMI of 25–29.9) have too much body weight for their height.

BMI is calculated by taking person’s weight (in kg and gm) and dividing by hieight (mt and cm) square. Example : For instance, if your height is T65 mt, the divisor of the calculation will be (1-65 x 1-65) = 2-7225, If your weight is 50-5 kg then your BMI is 18-54 = (2-7225 – 50-5).

Body Mass Index (BMI) = (weight (kg) / height (m2) Example: Your weight = 68 kg / Your height = 1.65 m (165 cm) BMI Calculation: 68 ÷ 1.652 = 24.98.

The BMI is universally expressed in kg/m2, resulting from mass in kilograms and height in metres. If pounds and inches are used, a conversion factor of 703 (kg/m2)/(lb/in2) must be applied. When the term BMI is used informally, the units are usually omitted.

Height: Weight: Your BMI is , indicating your weight is in the category for adults of your height. For your height, a normal weight range would be from to pounds….Adult BMI Calculator.

For most adults, an ideal BMI is in the 18.5 to 24.9 range. For children and young people aged 2 to 18, the BMI calculation takes into account age and gender as well as height and weight. If your BMI is: below 18.5 – you’re in the underweight range.

Height and Weight Chart

Here are general guidelines.

1. If your BMI is less than 18.5, it falls within the “underweight” range.
2. If your BMI is 18.5 to 24.9, it falls within the “normal” or Healthy Weight range.
3. If your BMI is 25.0 to 29.9, it falls within the “overweight” range.
4. If your BMI is 30.0 or higher, it falls within the “obese” range.

According to the National Institutes of Health (NIH) : A BMI of less than 18.5 means that a person is underweight. A BMI of between 18.5 and 24.9 is ideal. A BMI of between 25 and 29.9 is overweight.
