Convert circular mil to square chain
Please provide values below to convert circular mil [circ mil] to square chain [ch^2], or Convert square chain to circular mil.
1 circ mil = 1.2521e-12 ch^2. To convert circular mil to square chain, multiply the value by 1.2521e-12; to go the other way, divide by it (1 ch^2 = 798657329942 circ mil). Both units measure area and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 circ mil = 1.2521e-12 ch^2
- 1 ch^2 = 798657329942 circ mil
- 10 circ mil = 1.2521e-11 ch^2
- 100 circ mil = 1.2521e-10 ch^2
How to Convert Circular Mil to Square Chain
1 circ mil = 1.25210144890561e-12 ch^2

Circular Mil
A circular mil is a unit of area used to measure the cross-sectional size of wires, representing the area of a circle with a diameter of one mil (one thousandth of an inch).
History/Origin
The circular mil originated in the electrical industry to specify wire sizes before the adoption of metric units. It has been a standard measurement in North America for wire gauge sizes for many decades.
Current Use
Circular mils are still used today in the electrical industry to specify wire cross-sectional areas, especially in North America, although metric units are increasingly common.
Square Chain
A square chain (ch^2) is a unit of area equal to the area of a square with sides measuring one chain (66 feet) each, equivalent to 4356 square feet.
History/Origin
The square chain originated in land measurement practices in England, particularly used in surveying and land division during the 19th century, especially in the context of the Imperial system.
Current Use
Today, the square chain is largely obsolete and rarely used outside historical or land survey contexts; modern measurements typically employ acres or square meters.
Frequently Asked Questions
