Hello,

further down the article there are also listings for various HP calculators. And also the (rather simple) equation that needs to be computed. Unfortunately the coefficients used in this equation are based on all-American units like "BTU per square feet" which would require lots of unit conversions if this was to be used in the metric part of the world...
