How do I know the equivalent value for my conversion?

A. First, decide on the range that you want to show. For example, you might want to show 0 to 100 lb, or perhaps 500 to 1000 lb. Then, look up the equivalent values for this range for the other scale. You could look this up in a reference book, or there are many web sites that provide this sort of information. So for our example, it could be 0 - 45.359237 kg, or 226.796185 - 453.59237 kg. Enter these values for the Minimum Value and Maximum Value of the second scale. That's it. Once you've entered these numbers, you've got quick and easy conversion in the range of data that you need.
