Pressure/Altitude/Lift Calculator
This is an Excel version of my pressure to altitude, altitude to pressure and high altitude lift calculator. A javascript version of the pressure altitude convertor appears in the Software part of this website.

I have validated the pressure to altitude and altitude to pressure worksheets against other web based tools and they seem to be accurate and the lift calculator agrees in the lower levels at least with a variety of manufacturers load charts.

The lift calculator runs up to 70,000 feet. I am happy to amend it for anyone who is seriously going higher.
