If you look up "Mars" on the Wikipedia (or some other source), and specifically look for "Surface gravity", you will see that it is 3.711 meter / second squared. This is equivalent to 3.711 newton / kilogram. That is, each kilogram has a weight of 3.711 newton.
On Mars, you'd weigh 41.04 pounds.
On Mars, gravity is about 38% of Earth's gravity. If you weigh 90 pounds on Earth, you would weigh around 34.2 pounds on Mars.
If you weighed 78 pounds on earth, you would weigh 29.4 pounds on mars.
A camel typically weighs between 400 to 600 kilograms, depending on the species and age.
A man on Mars would weigh 38% of his weight on the Earth. This means that to find out a man's weight on Mars, you have to multiply their weight by 0.38. example: 100 pound man on the Earth weighs 100 X 0.38 = 38 pounds on Mars
On Mars, your weight would be about 10.26 kilograms due to the weaker gravitational pull compared to Earth.
175.4 kilograms
The weight of Mars with you would be the combined weight of your 201 pounds and the mass of Mars, which is approximately 639 quadrillion kilograms. To calculate the total weight, you would need to convert your weight to the equivalent mass in kilograms and then add it to the mass of Mars.
That depends on where you weigh 142 pounds.-- If you weigh 142 pounds on Earth, then your mass is 64.4 kilograms. (rounded)-- If you weigh 142 pounds on the Moon, then your mass is 389.2 kilograms. (rounded)-- If you weigh 142 pounds on Mars, then your mass is 169 kilograms. (rounded)-- If you weigh 142 pounds on Jupiter, then your mass is 24.4 kilograms. (rounded)...etc.
