Metal Pipe Tuner
This handy tool helps you calculate the length of a pipe based on a desired frequency, once you have found the calibration constant for your pipe material. To calibrate, cut any length of pipe and precisely measure its length and frequency. Enter these numbers into the Calibration form and tap / click on Calibrate. This will generate the calibration constant for your pipe material. Then you can select a note and click "Calculate Pipe Length" to obtain the theoretical length based on your note selection. I recommend actually cutting your pipe a little longer and then fine-tuning from there.

The math involved in these calculations is described in the Pipe Tuning handout which can be accessed here:
