Convert barn to square mil
Please provide values below to convert barn [b] to square mil [mil^2], or Convert square mil to barn.
1 b = 1.5500e-19 mil^2. To convert barn to square mil, multiply the value by 1.5500e-19; to go the other way, divide by it (1 mil^2 = 6.4516e+18 b). Both units measure area and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 b = 1.5500e-19 mil^2
- 1 mil^2 = 6.4516e+18 b
- 10 b = 1.5500e-18 mil^2
- 100 b = 1.5500e-17 mil^2
How to Convert Barn to Square Mil

Barn
A barn is a unit of area used primarily in agriculture to measure land, especially for farming purposes.
History/Origin
The barn originated as a unit of measure in the 19th century, based on the amount of land that could be covered by a barn, roughly equivalent to 40 square rods or about 40 acres, and was used in land surveying and farming contexts.
Current Use
Today, the barn is largely obsolete as a formal measurement unit but is still used colloquially in agriculture to refer to land area, especially in the United States, often informally approximating 40 acres.
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.
