Quick Answer: Why Is Weight In Kg?

What is the weight of a 70 kg person?

For example on earth a 70kg person would weigh 686N (70kg x 9.8 ) whereas on the moon, where the gravitational acceleration is about 1.62 , that same 70kg person would weigh 113N.

This means on a pair of scales calibrated for earth they would measure 11.5kg.

G-force is another name for the acceleration due to gravity..

How can I calculate weight?

The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms. The Newton is the SI unit for weight, and 1 Newton equals 0.225 pounds.

What is SI unit of weight?

The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 x 10–34 when expressed in the unit J s, which is equal to kg m2 s–1, where the metre and the second are defined in terms of c and Cs.

What is the weight of a 75 kg person?

We know that 1 kg≈2.2 lbs . The actual value is around 165.34 lbs .

What is 1kg force?

It is equal to the magnitude of the force exerted on one kilogram of mass in a 9.80665 m/s2 gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). That is, it is the weight of a kilogram under standard gravity.

What is my ideal weight in kg?

Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.

What is correct weight and height for age in KG?

What is the weight of a person with a mass of 75 kg?

So weight = 9.8 x 75 You can get your answer in Newton. What is the weight of 1 kg mass of an object on Earth?

Why is weight measured in kg instead of Newton?

Weight, instead, corresponds to the resultant force of the action exerted by gravity of the Earth (in our case) on the mass of a body, and its measuring unit is Newton (N) at the ISU. … Thereby, weight of an object becomes mass in an easy way. And that’s how we “weight” in kg.

Is weight measured in kg?

Yes. When we use kilograms to measure weight, we are actually referring to kgf or kilogram-force. From Wikipedia: One kilogram-force is equal to the magnitude of the force exerted by one kilogram of mass in a 9.80665 m/s2 gravitational field. In other words, the weight(force) of one kg is equal to one kgf, or 9.8N.

What type of force is weight?

Many students of physics confuse weight with mass. The mass of an object refers to the amount of matter that is contained by the object; the weight of an object is the force of gravity acting upon that object.

What is a healthy weight?

It measures a person’s weight in relation to their height. 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.

What is the weight in moon?

Your weight on the Moon is 16.5% what you would experience on Earth. In other words, if you weighed 100 kg on Earth, you would weigh a mere 16.5 kg on the Moon. For you imperial folks, imagine you tipped the scales at 200 pounds. Your weight on the Moon would only be 33 pounds.

What is 1 kg in Newtons?

about 9.8At average gravity on Earth (conventionally, g = 9.80665 m/s2), a kilogram mass exerts a force of about 9.8 newtons.

Is weight in newtons or KG?

The kilogram is not actually a unit of weight, although people use it as such. It is actually a measure of mass, measurable only because we rarely need to have a force of gravity other than Earth’s. The Newton is the real measure of weight, although it is used almost never. So 70 kg is your mass, not your weight.

Is weight a force?

Weight is a force acting on that matter . Mass resists any change in the motion of objects. In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity. Weight is measured in newtons.

Is weight and force same?

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 does kilo mean?

kilo- a Greek combining form meaning “thousand,” introduced from French in the nomenclature of the metric system (kiloliter); on this model, used in the formation of compound words in other scientific measurements (kilowatt).
