Spike's Calculators

Calculate a pipe's bend radius using the curve's internal angle and the bend's length. This calculator uses inches for measurements.

- enter the angle of the curve in degrees
- the length of the curve in inches
- decimal precision, number of digits after the decimal point

- the bend radius in inches

r = 0.5L/sin(a/2) where r is the bend radius L the bend length the internal angle of the curve
