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, gravity is about 38% of Earth's gravity. If you weigh 90 pounds on Earth, you would weigh around 34.2 pounds on Mars.
On Mars, you'd weigh 41.04 pounds.
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.
Mars has a lower density and is also about half the size of the earth. the resulting combination leaves mars with a much less gravitational pull (about 62% less). This means that someone weighing 160 lbs on earth would weigh about 61 lbs 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.

If you weigh 31 kilograms, you would weigh approximately 68.3 pounds.
The package weighs 5 kilograms.
If a person weighs 84 kilograms, they would weigh approximately 185 pounds.

On average, great white sharks normally weigh about 2240-2268 kilograms
100 pounds = 45.36 kilograms.
You are weightless on mars because there is zero (or no) gravity.
