Calculate

AWG Size:

The Circular Mils to AWG Calculator helps users convert circular mils (CM) to American Wire Gauge (AWG), a standardized wire sizing system. This conversion is crucial in electrical engineering and wiring applications.

Formula

The formula to convert circular mils to AWG is:

AWG = 39 − (log₁₀(CM) / log₁₀(92)) × 19

How to Use

1. Enter the circular mils (CM) value in the input field.
2. Click the “Calculate” button.
3. The corresponding AWG size will be displayed.

Example

• Input: 10,380 CM
• Calculation: AWG = 39 − (log₁₀(10,380) / log₁₀(92)) × 19
• Output: 10 AWG

FAQs

1. What is AWG?
   AWG (American Wire Gauge) is a system used to define wire diameter.
2. Why convert circular mils to AWG?
   It standardizes wire sizing for electrical applications.
3. What is a circular mil?
   A circular mil is a unit measuring wire cross-sectional area.
4. Is AWG size inversely proportional to wire diameter?
   Yes, a lower AWG number means a thicker wire.
5. Can I use this calculator for all wire types?
   It applies to electrical wires following the AWG standard.
6. What is the smallest AWG size?
   The smallest standard AWG size is 40 AWG.
7. What is the largest AWG size?
   The largest standard AWG size is 0000 (4/0) AWG.
8. Does insulation affect AWG size?
   No, AWG only measures the conductor diameter.
9. What happens if I input a negative value?
   The calculator will return “Invalid input.”
10. Can I calculate AWG from square millimeters?
    No, this calculator specifically converts from circular mils.
11. What is the relationship between CM and mm²?
    1 circular mil = 0.0005067 mm².
12. Are metric wire sizes different from AWG?
    Yes, metric wires use square millimeters (mm²).
13. How accurate is the AWG conversion?
    The formula provides precise AWG sizes for standard use.
14. Does higher AWG mean more resistance?
    Yes, higher AWG wires have greater electrical resistance.
15. Why is AWG important in electrical systems?
    Proper wire sizing ensures safe and efficient power transmission.
