Answer 1:
551.1557 lbs.
Answer 2:
An oddly phrased question.
On Earth, a person massing 250 kilograms also weighs 250 kilograms. Or 550 pounds.
On the moon, he would weigh about 1/6th that amount. On Mars, about 1/3rd that amount. In free fall, he would weigh zero kilograms.
His mass would of course always remain the same.
Multiply the mass in kilograms by 9.8 (units are meters/second2, or the equivalent newtons/kg). Answer is in newtons.
On Earth, 25 kg of mass weighs 55.12 pounds (245.2 newtons).
250 kilograms is the mass

The speed of a falling object keeps changing as it falls. If an object falls 250 feet to the ground and there is no air, then it takes about 4 seconds to fall, and it hits the ground at about 86.5 miles per hour (127 fps). If the object falls through air, then the speed it picks up depends on its weight and shape ... a sailplane falls slower through air than a rock does, but take away the air, and a rock and a feather fall together.
The weight of Jupiter is 85 earth pounds earth weighs 6,000,000,000,000,000,000,000,000 (6E+24) kilograms.or 6*6*6 so on 24 times
250 Newtons converted into mass is 25.5 kilograms
Density is equal to mass divided by volume (d= m/v). So m= 250 g and v = 125 cm cubed (cm3), there fore density is 2 g/cm3.
32 ft per second squared- However, due to air resistance, the final speed will top out at about 250 mph for a streamlined object.
The mass of an object stays the same no matter where it is, as it still has the same amount of matter in it (the definition of mass is the amount of matter in an object). However, the weight of an object changes based on the gravitational pull of the celestial body it is on. The equation W = m * g where W is the weight, m is the mass of the object, and g is the gravitational acceleration of the celestial body (which changes from body to body) shows that an object's weight would change with the planet's gravitational acceleration. For example, the gravitational acceleration is 9.8 m/s^2 on Earth, and the gravitational acceleration on Jupiter is about 25m/s^2. So let's work out the equations with a 100 kg mass. Earth: W=mg W=100kg*9.8m/s^2 W=98 kg/m/s^2 or 98 newtons Jupiter: W=mg W=100kg*25m/s^2 W=250 kg/m/s^2 or 250 newtons So, (250/98 = ~2.5) things weigh about 2.5 times more on Jupiter, but have the same mass.

On Earth only, 250 grams of mass weighs about 8.82 avdp ounces.
Moon weight is approximately 1/6 of Earth weight. So 250 divided by 6 is about 41.5. Nice diet!
250 pounds
For standard water under standard conditions ... 1 liter of water has 1 kilogram of mass ===> 250 liters has 250 kg of mass. On the surface of the earth, 1 kg weighs 2.20462 pounds ===> 250 kg weighs (250 x 2.20462) = 551.155 pounds
The Greeks about 400 BCE first determined the distance to the moon, sort of. They did this by noting the ratio of the time it took earth's shadow to cross the lunar surface to the length of time of the lunar orbit. The ratio was about 60 to 1, indicating the moon was 60 earth diameters away. The earth's diameter is about 8000 miles, so the lunar distance is roughly 240,000 miles. What the Greeks did NOT know was what the earth's diameter was, so they really didn't know, at least for about 200 years, how far away the moon REALLY was. Finally, about 250 BCE, Eratosthenes determined the diameter of the earth, and the last bit of information fell into place.
You need to use density. What are you converting?

There are lots of ifs in this question and answer. If the 100 pound Earth object could rest on the outer surface of Jupiter the answer would be 250 pounds. But, Jupiter is a gas planet. That is, Jupiter is primarily made of gas and liquid. So, the object could not rest on the outer surface. There may be a solid surface near it's center but no one knows. Jupiter is 318 times as heavy as Earth so if Jupiter were solid and the size of Earth the object would weigh 318 times a much or 31,800 pounds. But, it is much larger than Earth so the outer surface is much farther from the center. The farther away the object is from the center the less the object will weigh.
Martian gravity is 38% of Earth's gravity. 38% of a 250 pound person's weight would be (250 x .38) 95 pounds.
