Weight is a measure of the force of gravity acting on an object's mass. In this case, 144 kilograms (kg) is a measure of mass, not weight. Weight is calculated by multiplying mass by the acceleration due to gravity, which is approximately 9.81 m/s^2 on Earth. Therefore, the weight of a 144 kg object on Earth would be approximately 144 kg * 9.81 m/s^2 = 1412.64 Newtons.
Answer #1:1 kg =2.2 pounds75/2.2 = 34.09 kg===================================Answer #2:"Pound" is a unit of weight. "Kg" is a unit of mass. They don't direcly convert,and their relationship depends on where the mass happens to be located atthe time.-- On Earth, 75 pounds is the weight of about 34.019 kg of mass.-- On the moon, 75 pounds is the weight of about 205.563 kg of mass.-- On Mars, 75 pounds is the weight of about 89.903 kg of mass.-- On Jupiter, only about 13.458 kg of mass weighs 75 pounds.
This is not a valid conversion; kilograms (kg) and grams (g) are measures of weight or mass while milliliters (mL or ml) measure volume.
Close to the Earth's surface, each kilogram has a weight of about 9.8 newton. Thus, you must simply multiply the mass by 9.8 (newton/kilogram).
Oh, dude, weight and mass are like two peas in a pod, but not quite. Weight is the force of gravity acting on an object, so if the weight is 490 N, the mass would be 490 divided by the acceleration due to gravity (9.8 m/s^2), which is about 50 kg. So, yeah, that's the mass, but who's really keeping track, right?
