His weight depends on where he is, because
Weight = (mass) x (gravity in the place where the mass is) .
For example:
— If this man is on Mars, his weight is (110 kg) x (3.7 m/s²) = 408 Newtons
— If he is on the Moon, his weight is (110 kg) x (1.6 m/s²) = 176 Newtons
— If he is on Earth, his weight is (110 kg) x (9.8 m/s²) = 1,078 Newtons
— If he is in a spacecraft coasting from one to another, his weight is zero.
