## About
Functional threshold power, or FTP, is the highest power you can hold for about an hour. The Cycling FTP Power Zones Calculator turns it into the seven training zones in the widely used Coggan system, shows your watts per kilogram, and can estimate FTP from a 20-minute test as 95% of your average power. Zones are percentages of FTP, so a correct FTP matters more than anything else.

## How to use
1. Choose whether you know your FTP or have a 20-minute test result.
2. Enter your FTP, or your average power from the test.
3. Enter your weight to see watts per kilogram.
4. Read the seven zones in watts and use them to set training intensity.
