Convert square mil to square chain
Please provide values below to convert square mil [mil^2] to square chain [ch^2], or Convert square chain to square mil.
1 mil^2 = 1.5942e-12 ch^2. To convert square mil to square chain, multiply the value by 1.5942e-12; to go the other way, divide by it (1 ch^2 = 627264000000 mil^2). Both units measure area and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mil^2 = 1.5942e-12 ch^2
- 1 ch^2 = 627264000000 mil^2
- 10 mil^2 = 1.5942e-11 ch^2
- 100 mil^2 = 1.5942e-10 ch^2
How to Convert Square Mil to Square Chain

Square Mil
A square mil is a unit of area equal to the area of a square with sides measuring one mil (thousandth of an inch).
History/Origin
The square mil has been used primarily in engineering and manufacturing to measure very small areas, especially in fields like electronics and materials science, where precision at a microscopic scale is required.
Current Use
Today, the square mil is mainly used in the electronics industry to specify the cross-sectional area of wires and conductors, as well as in materials science for measuring tiny surface areas.
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.
