Weight  is directly proportional to the acceleration of gravity wherever you happen to be at the moment.

If the backpack weighs 300 lb on Earth, and you take it to a place where gravity is 37.9% of Earth's gravity, then the backpack will weigh

(37.9%) x (300 lb)

(0.379) x (300 lb)

That's 113.7 lb.
