 # How Can I Calculate Weight?

## What is value of G?

Its value is 9.8 m/s2 on Earth.

That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2.

When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location..

## What is SI unit of weight?

The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.

## How do you calculate weight in kilograms?

To convert pounds to kg, multiply the pound value by 0.45359237 or divide by 2.2046226218. For example, to calculate how many kilograms is 50 pounds, multiply 50 by 0.45359237, that makes 22.6796 kg is 50 lbs.

## How much does a 3 bedroom house weigh?

However, if you are looking for a quick over the phone estimate, you can tell them that your three bedroom house weighs about 5,000 pounds. To calculate the volume of your furniture, you should use a tape measure to take measurements.

## What is the Newton formula?

1 Newton = 1 kg • m/s2 The definition of the standard metric unit of force is stated by the above equation. One Newton is defined as the amount of force required to give a 1-kg mass an acceleration of 1 m/s/s.

## How do you calculate weight to height?

Updated Equations for Ideal WeightWeight in pounds = 5 x BMI + (BMI divided by 5) x (Height in inches minus 60)Weight in kilograms = 2.2 x BMI + (3.5 x BMI) x (Height in meters minus 1.5)

## What is the heaviest thing on earth?

In terms of actual weight, the heaviest object ever directly weighed, according to Guinness World Records, is the revolving service structure of the launch pad at the Kennedy Space Center in Florida, clocking in at 4.86 million pounds.

## How much does a 1000 square foot house weigh?

Rules of thumb around the construction industry are 200 pounds per square foot for a single-level home, 275 for two levels and 350 for three levels. This figure is predicated on no heavy features such as tile roofing or extensive masonry work, but includes foundation.

## How 9.81 is calculated?

The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.

## What is the formula for weight?

The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.

## How do you calculate the weight of an object?

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.

## What is my weight for my age?

Three simplified linear equations were derived to calculate mean weight for age. For Infants < 12 months: Weight (kg) = (age in months + 9)/2 For Children aged 1-5 years: Weight (kg) = 2 x (age in years + 5) For Children aged 5-14 years: Weight (kg) = 4 x age in years.

## What is gravity’s formula?

The formula is F = G*((m sub 1*m sub 2)/r^2), where F is the force of attraction between the two bodies, G is the universal gravitational constant, m sub 1 is the mass of the first object, m sub 2 is the mass of the second object and r is the distance between the centers of each object.
