This table contains conversion factors for various units.
A spreadsheet is available for purchase that uses advanced techniques to combine units for conversion. It can be called from other spreadsheets and manipulated in a consistant, comfortable format. Units are entered as text strings with standard math operators. The spreadsheet checks to ensure that units are properly formed.
Go to the Activation link to order the evaluation spreadhseet. It can be downloaded and used for a trial period. You can select a PayPal button for an activation code to eliminate the trial period limit. The code will be emailed to you within 48 hours of payment approval.
