The person who marked this motor didn't fully understand the difference between mass and force, and the use of a '-' instead of a '*' makes things even worse. The unit kg-cm (mass minus distance???) doesn't make any sense.
What is meant is the weight of the mass 1 kg times the distance of 1 cm - i.e. torque. Since the force of weight of 1 kg is about 9.81 N, this becomes about 3.18 Nm or about 450 oz*in, in units of torque.
My guess is also that the 'min' means minimum.
