Calculate Turns

JAVATC performs millions of iterations for accuracy during the total system computations (it takes time). This quick calculator is available for coilers who need to equate the number of turns, radius, height, etc. accurately for their primary or secondary coils.

This calculator will equate all linear geometry's (flat, helical, cones, and inverse cones), closewound or spacewound.

Use any unit you prefer (inches, meters, etc.), just be sure ALL units are the same for ALL inputs.
The wire table for secondary coils list inches. Convert values to your unit as necessary.
Due to manufacturer variations in insulation, measuring wire dimensions with a caliper is preferred over any wire table.

For primary's with bare wire (copper tubing, etc.), set insulation to 0
