Rood


A rood is a historic unit of area used primarily in England and some other countries for measuring land.



  • 1 rood = 1/4 of an acre



  • 1 rood = 10,890 square feet ≈ 1,012 square meters



  • 4 roods = 1 acre



The rood was traditionally used for measuring small plots of land, especially in farming and real estate.


Circular Mil


A circular mil is a unit of area used mainly to measure the cross-sectional area of round wires and cables in electrical engineering.



  • Defined as the area of a circle with a diameter of 1 mil (1 mil = 0.001 inch).



  • Area = (diameter in mils)² circular mils.



  • 1 circular mil ≈ 7.854 × 10⁻¹⁰ square meters or 0.7854 square mils.



Circular mils simplify calculations for round wires since area scales with the square of the diameter.
