Ah, let's paint a happy little picture with numbers, shall we? If a chair has a mass of 90 kilograms, we can find its weight by multiplying the mass by the acceleration due to gravity, which is about 9.8 meters per second squared. So, the weight of the chair would be around 882 Newtons. Just a gentle reminder that every object, no matter how heavy, has its place in this beautiful world.
Mass is a quality of matter (apparently a construct of the Higgs field, but that's probably a little more answer than you were looking for). Weight is mass acted on by gravity. Mass is usually stated in units of kilograms. Weight can also be stated in kilograms, but is sometimes expressed in newtons. The mass stays constant, while the weight can change. If you are 90 kg, then on the moon your mass would still be 90 kg, but your weight would be one sixth of that, 15 kg. Weight is the force of attraction exerted on you by the moon or the earth, whichever you happen to be standing on. In science and engineering mass is described in kilograms, while weight (force) is measured in Newtons which goes back to Newton's second law of motion: force equals mass times the rate of change of momentum. In most cases that can be simplified to force equals mass times acceleration. A force of 1 Newton causes a 1 kg mass in free motion to increase its speed by 1 meter per second every second. In practice on the earth's surface a 1 kg mass has a weight of 9.81 Newtons, but in everyday language we say its weight is 1 kg because that works for everyone who is not an astronaut :).
To convert 90 kg to newtons, you would multiply by the acceleration due to gravity (approximately 9.81 m/s^2). So, 90 kg is equal to 90 x 9.81 = 882 Newtons.
Micrograms is a measure of weight or mass. 90 micrograms is equal to about 0.000003175 ounces.
90 weight oil corresponds to SAE 90 oil, which means it has a viscosity rating of 90. The weight of the oil is measured in centistokes at 100°C, which helps to determine how thick or thin the oil is. However, the weight of the oil in pounds depends on the volume of oil you are referring to.
A healthy weight range for a 12-year-old who is 5'0" can vary, but it is generally around 90-110 pounds. It's important to remember that weight can fluctuate based on muscle mass, body composition, and other factors. Consulting with a healthcare provider is recommended for personalized advice.
A student with a mass of 90 kg on the earth (gravity =9.8m/s/s) will have a weight of 882 Newtons. Weight = Mass * Gravity
A mass of 90 kg weighs 882 newtons (198.4 pounds) on the earth. (rounded)
The weight of a 90-kg astronaut on Earth would be approximately 882.9 Newtons (N). This is calculated by multiplying the astronaut's mass (90 kg) by the acceleration due to gravity on Earth (9.81 m/s^2).
On earth, 90 kg of mass weighs 882 newtons.
Weight = m g = (90 x 10) = 900 newtons
On my planet a man with a mass of 90 kg has a weight that is also 90 kg. On the Moon the same 90 kg man has a weight of 15 kg because the Moon is smaller and has less gravity. We distinguish between mass (amount of matter) and weight (a downward force) so that mass stays the same wherever the man is, even if his weight changes. Since Isaac Newton's time we know that force is equal to mass times acceleration, and the unit of force is defined technically as the force that accelerates a mass of 1 kg by 1 metre per second, every second. That amount of force is a Newton. If a 1-kg mass is dropped it will accelerate downwards at 9.806 metres per second per second, therefore the force on it is 9.806 Newtons. So the weight of a 90 kg man is technically described as 90 x 9.806 Newtons, in other words 882 Newtons. On the Moon his mass is still 90 kg but his weight is now only 147 Newtons.

From Newton's second law, F=m*a (net force is the product of mass and acceleration).The mass here is 45 kg, and the acceleration is 2m/s2.Multiply the two together.
To convert 90 kg to newtons, you would multiply by the acceleration due to gravity (approximately 9.81 m/s^2). So, 90 kg is equal to 90 x 9.81 = 882 Newtons.
10 chairs!
The person would be about 89 kilograms in weight. The person would still have a mass of 100 kilograms, of course. The strict scientific unit of weight is the "newton" because that is the unit of force and weight exerts a force. The 100 kg person weighs 890 newtons on Venus. However, normally we say "kilograms" or "kilograms weight", as long as we are clear that weight and mass are different.
The angle of the backs of chairs are at an obtuse angle to the seat. There are some straight back chairs that are 90 degrees but most are over 90 degrees.
