Approximately 53.6 lb.
According to several sources (compiled below), the acceleration due to gravity on the surface of Mars is about 3.7 m/s^2. Since F = ma, the weight of an object is proportional to its acceleration, so a 142 lb object on the Earth (whose acceleration is 9.8 m/s^2) would weigh 3.7/9.8 x 142, or 53.6 lb.
BTW, weight is a measure of force and "pound" is a unit of force. The English unit for mass is "slug". Part of the confusion comes from using the unit "gram" (or "kilogram") when specifying weight and saying that 2.2 kg equals 1 lb. Technically, that is not correct. One is a measure of force and the other is a measure of mass. 2.2 kg weighs 1 lb on the surface of the Earth, but it weighs less on Mars.

between 53.392 pounds and 53.5 pounds
mars has a gravity approximately equal to .376ths that of earth.
multiply 142 X .376 and you've got your answer in pounds
now .376 is still an apporximation.....
and most online sources even round it up to .38
which would give you 53.96 pounds, but this is definitely incorrect.
I think .3765 is a better choice and results into 53.463 pounds
but then again,
you get all kinds of mars gravity quotes online ranging from .372 .375 .38 and .39
SOOOO it all depends on where you get your info from.

142lbs - mass doesnt alter, and pounds is a unit of mass
