What is the formula used to calculate density?
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.
What is SI unit of weight?
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).
What is the formula for weight in physics?
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 is the height formula?
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.
What is height/weight ratio?
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.
What is the formula for calculating BMI class 11?
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).
How do you calculate BMI example?
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.
How do you calculate BMI and write down all categories?
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.
