Doing a Google on Mars and Gravity, I see that Mars has about 1/3
the gravity of Earth, so a person weighing 100 pounds on Earth
would weigh about 33 pounds on mars.

7.14 stones

From Ken Croswell's beautiful book
Magnificent
Mars, page 6:

"If you weigh 100 on Earth, you'd weigh only 38 on Mars."

Later in the book Dr. Croswell notes that one reason the mountains on
Mars are so tall is because gravity is weaker, allowing the Martian
crust to support such mighty structures.

Sorry for the double post. The first time I posted I got an error
message, but apparently it worked just fine.

And apologies in advance if this apology comes out in duplicate!

Isn't 100 pounds a mass? Masses dont change when you take em to mars right?
.... The force on which the mass is pulled down in Newton would be less
ofcourse. So if someone on earth has a mass of 100 pounds and "g" is 9.8
he's pulled down by 980 Newton. This would be less on mars cause it's
constant "g" would be less.

pounds are weight. slugs are mass (in english units)
kilograms are weight. newtons are mass (in mks)

F=MA

lbs= slugs*ft/sec^2

kgs= newtons*m/sec^2

slugs are so useless, i'm digging deep into the memory banks to come
up with the weight equivalent. ummm. 32 pounds at earth gravity.

to the following posters, yeah, mars gravity is about 1/3 earth's.

33 pounds on mars. plus or minus.

How much would a person weighing 12 and half stone weigh on the moon.

(that's my weight)
