53kg equates to about 520 newtons (on Earth).
If your weight on Earth is 545 newtons then on the moon your weight will be 1/6 as much or about 9.6kg
not weight, but a little less than 6 newtons
'Kg' is a unit of mass, not weight. On Earth, 1 kg of mass weighs 9.8 newtons, and 1 newton is the weight of about 0.102 kg of mass. On the moon, the same kg of mass weighs 1.6 newtons, and 1 newton is the weight of about 0.616 kg of mass. On Mars, the same kg of mass weighs 3.7 newtons, and 1 newton is the weight of about 0.269 kg of mass.
Weight in Newtons = mass in kg x acceleration due to gravity W = 1kg x 9.8m/s2 = 9.8N
The weight you specify refers to the weight on Earth (in Newtons, and assuming a gravity of 9.8).
The mass of this barbell is 115 kg. This means that on earth, the weight of the barbell in Newtons is equal to m*g or 115 kg * 9.8 m/s^2. The weight of this barbell is 1.13 kN.
Mass experiences about 1.62 Newtons per kilo on the lunar surface. Hence a 70 kg man would "weigh" only 113.4N.
On Earth, 1,500 kg of mass weighs 14,710 newtons.
588.399 newtons. (60 * 9.80665)
