Spike's Calculators

Calculate the internal angle of a curved section of pipe using the bend radius and the length of the curve. This calculator uses inches for measurements.

- enter the length of the curve in inches
- the bend radius in inches
- decimal precision, the number of digits after the decimal point

- the internal angle in radians
- in decimal degrees
- in degrees, minutes, and seconds

a = sin^{-1}(d/r) where a is the angle in radians d half the length of the curve r the bend radius

- Bend Radius and Angle
- Curved Pipe Volume
- Internal Angle from the Bend Radius
- Pipe Bend Radius Calculated from an Angle
- Pipe Volume from Curve Length and Height
- Pipe Volume
