Multiplier For A 10 Degree Bend
Multiplier for a 10 degree bend is fast with WireGaugeCalc, since you pick the bend angle and the tool returns the offset multiplier and shrink.
It uses the trigonometry behind conduit bending, so you mark distance between bends without guessing.
You get the multiplier and shrink per inch in seconds, so a shallow offset clears an obstruction on the first try.

Ohm’s law: V = I × R and P = V × I. Field aid only, verify against the current NEC and your local authority having jurisdiction.
Offset multiplier and shrink for a shallow conduit bend
The multiplier comes from the cosecant of the bend angle, so a 10 degree bend gives a large multiplier of about 6.0.
Since the angle is shallow, the distance between bends is long, but the shrink stays small at roughly 1/16 inch per inch of offset.
The calculator pairs the multiplier with the shrink, so your conduit lands on the box without creeping short or long.
What the 10 degree offset bend math gives you
Enter the offset and angle and the tool returns the marks:
- Multiplier of about 6.0 for a 10 degree bend
- Distance between bends from offset times the multiplier
- Shrink of roughly 1/16 inch per inch of offset
- Adjusted start mark so the run ends on target
- Same method for 22.5, 30, 45, and 60 degree bends
One app for every NEC calculation
WireGaugeCalc keeps the calculations you reach for most in one place:
- Voltage drop and wire sizing for any run
- Conduit fill for EMT, PVC, and RMC
- Box fill and junction box sizing
- Ampacity and temperature derating
- Motor circuit and load calculations
- Conduit bend offsets and saddles
Built for the field, works offline
The whole app runs on your phone, so it keeps working in a basement, an attic, or a job site with no signal.
There is no account to create and nothing to load. Open it, run the number, and get back to work.
- No signup and no signal needed
- Answers in a tap, not a spreadsheet
- Same tool on phone, tablet, and desktop
Every result cites the NEC article
Each answer shows the table or formula it came from, so you can check the method and learn the code as you go.
That makes the app useful on the job and during exam prep, since the reasoning is right next to the number.
Switch the code year your job runs on
Jurisdictions adopt the NEC at different times, so you can match the calculation to the code in force:
- NEC 2017, 2020, and 2023 tables
- Copper and aluminum conductors
- 60, 75, and 90 degree C terminations
- Single-phase and three-phase systems
Run the number, then get back to work

What is the multiplier for a 10 degree bend?
A 10 degree bend uses a multiplier of about 6.0, which is the cosecant of 10 degrees. Multiply your offset depth by 6.0 to find the distance between the two bends.
Why pick a 10 degree bend instead of a steeper one?
A shallow 10 degree bend produces little shrink and an easy pull, so it suits long, low offsets where space allows. Confirm conduit support and bend rules against the current NEC and your local authority having jurisdiction.
Is WireGaugeCalc free to use?
Yes. Every calculator is free to run with no signup. A paid tier adds saved projects, PDF reports, and extra code years, but the core math stays free.
Does it work without internet?
Yes. The app runs on your device, so it keeps working with no signal on a job site, in a basement, or in an attic.
Are the results code accurate?
Results follow published NEC tables and standard formulas, and each answer shows the article it came from. It is a field aid, not a stamp of approval, so verify against the current code and your local authority before you wire anything.
Which NEC code year does it use?
You can switch between NEC 2017, 2020, and 2023, since jurisdictions adopt the code at different times. Pick the year your job runs on.
