Hello Everyone, Can Anyone Help Me with My K Factor Calculation?

[Mathuser01]

Hello everyone,

I am new to this group. I am an HTML web developer and have recently created a website with various factor calculators. One of the calculators I developed is a K Factor Calculator. Since I am not very proficient in math, I need your help to verify its accuracy.

I noticed that the results from my calculator differ from those of similar calculators on other websites. I am using the following formula to calculate the K Factor:

```
(Math.PI * insideBendRadius * bendAngle) / 180 + (sheetThickness * bendAngle);
const kFactor = (totalFlatLength - lengthA - lengthB) / (2 * Math.PI * insideBendRadius);
```

Could you please help me check if this formula is correct and let me know if there are any errors? Your assistance would be greatly appreciated.

Thank you!

If Math.PI = [imath]\pi[/imath] and bendAngle is given by degrees, the formula should be:

(Math.PI * insideBendRadius * bendAngle) / 180 + (Math.PI * sheetThickness * bendAngle) / 180

Or

[ (Math.PI * insideBendRadius * bendAngle) + (Math.PI * sheetThickness * bendAngle) ] / 180

Or

(Math.PI * bendAngle) (insideBendRadius + sheetThickness ) / 180
