Converting from the U.S. customary unit, pounds, to the metric unit, kilograms, is a simple unit conversion problem that requires knowing or having the ability to look up the conversion factor of pounds to kilograms and knowing how to properly set up and solve a conversion problem. In this case, there are .454 pounds for every 1 kilogram or 2.2046 kilograms for every 1 pound. This means that .454 lbs/1 kg = 1 lbs/2.2046 kg. Each of these fractions could also be inverted and would mean the same thing.

The common factor in this case is the unit "lbs." Cancel it out on each side of the equation and you are left with this: 195 x 1 kg/.454.
The final step is to simply do the math. You can multiply 195 by 1/.454 or simply divide 195 by .454. Either way, the result is the same. Be sure to carry over the new unit (kilograms) to your final answer.
