Circular Pitch Solution

Follow our step by step solution on how to calculate Circular Pitch?

FIRST Step Consider the formula

P c = π \cdot m

Next Step Substitute values of Variables

∴

P c = π \cdot 5.5mm

Next Step Substitute values of Constants

∴

P c = 3.1416 \cdot 5.5mm

Next Step Convert Units

∴

P c = 3.1416 \cdot 0.0055m

Next Step Prepare to Evaluate

∴

P c = 3.1416 \cdot 0.0055

Next Step Evaluate

∴

P c = 0.0172787595947439m

Next Step Convert to Output's Unit

∴

P c = 17.2787595947439mm

LAST Step Rounding Answer

∴

P c = 17.2788mm
