Welcome to the best electronics, power, mechanical and amateur radio site on the web. You will find many if not all of the frequently needed power conversion formulas here as well as other conversion, electrical, mechanical, motor power and force formulas. In addition, there is a wealth of amateur radio information. Please be sure to leave me feedback in the guestbook or send an email with your comments, suggestions and any corrections that you can offer. I do my best to be accurate but nobody is perfect. Please feel free to contact me if you need assistance with computing any power, force, temperature or other conversions. I'll do my best to help where I can.

This site contains significant technical information for electrical power computations and electrical power conversion formulas as well as calculators to provide results for many of the formulae. There is also plenty of conversion information regarding temperature, metrics and force. In addition, there is a wealth of information regarding Amateur Radio and antennas as well as a calendar of events.

Be sure to keep up with the pursuit of advancing the state of the art with our great amateur radio hobby! I would hate to see some commercial interest convince the government that the radio amateur service doesn't deserve the spectrum allocated to us. Above all simply operate all you can. I hear quiet bands out there (or maybe it's just the lack of sunspots?) and I have to wonder if some enterprising commercial endeavor will consume our spectrum.

Finally, be an Elmer!!! If W9FRT had not been patient and interested in me as a teen, I would probably not be a HAM today.

Electrical Conversion Formulae

This is one of the most popular sites on the web for power conversion formulas (according to Google rankings). Feel confident that the information presented here is accurate and reliable.

We Have A New Look!

We've reformatted the site and brought it up to w3c standards. Navigation is less confusing and the pages are cleaner while still containing the same useful information. This site is built with css, a little bit of java script and no frames.
