>VERY easy and clear to use. One suggestion, many countries (Canada, Australia and most of Europe) use the metric system. Any way of having another drop-down field with a choice of selection of eithermiles' or 'kilometres' ?(note the spelling of the latter - many incorrectly spell it ....kilometers)
No problem. In one part of the calculation I have to supply the approx. diameter of the earth in miles, which determines the final units. Replace it with the diameter in kilometers, and viola! I could even give it to you in feet, meters, AU's, carrots, etc. :)
Excellent suggestion!

p.s Merriam-Webster disagrees with your spelling of kilometer... http://www.m-w.com
