Hmmm, I think I know what you're trying to say here..you multiplied the mass by 10. What I think you are doing is calculating a force because 10 is awfully close to the acceleration due to gravity and some teachers just use 10 instead of 9.8. The units for force are Newtons (N) but they are kgm/s^2 so you'll have to convert your mass into kilograms first by dividing your mass by 1000
