Definition of the Circular Inch
A circular inch is the area of a circle with a diameter of 1 inch. The formula for calculating the area of a circle is:
Circular Inch Historical
The circular inch was introduced as a practical unit for measuring areas in contexts where circular cross-sections were common, such as:
- Pipe diameters
- Wire gauges
- Hydraulic and pneumatic systems
It instantly gained employment in engineering and manufacturing industries, especially in those areas of applications that entailed round features or hole measurement.
The circular inch, however, has no origin in the times of agriculture or the surveying of lands or parcels of land like the acre unit of measurement. It is relevant most to industrial and scientific purposes.
The circular inch is a relatively small unit, so its conversions to larger units of area are rarely used in practice. However, it can be expressed as:

circular inch = 0.7854
square inches1
circular inch ≈ 5.454 × 10⁻³
square feet1
circular inch ≈ 6.051 × 10⁻⁴
square yards1
circular inch ≈ 5.067 × 10⁻⁴
square centimeters
Use in Measurement Today
The circular inch remains relevant in engineering and manufacturing, particularly in the following areas:
- Hydraulics and Pneumatics: Employed in the determination of the area within cross section of pipes, cylinder and opens at a given moments. For use in calculation of fluid flow rates and pressure throughout various elements of a system.
- Wire and Cable Manufacturing: Usually used in the measurement of wire cross sections since circles are frequently the shapes of sections of wire.
- Mechanical Engineering: It used for designing and analyzing circular shaped members such as shafts, bearings, gears etc.
- Optics and Lenses: Proves quite valuable for designing circular openings and lens.
Notable Uses
- Industrial Design: The circular inch is useful for assessing the capacity and performances of circulation based systems that incorporate circular sections.
- Aerospace and Automotive: Applied in the construction of the engines, turbines and other round engine components.
- Electrical Engineering: Part of the process of defining the cross sectional area of wires thus affecting the current carrying capability.
Square Perch: A Comprehensive Explanation
Definition of Square Perch
A square perch is defined as an ancient method of measuring and is more predominantly associated with value estimation of land. It means the area of a square whose sides are of one perch in length with one perch = 16.5 feet, or 5 yards.
- 1 square perch = 272.25 square feet
- 1 square perch = 30.25 square yards
It is a smaller unit compared to the acre, often used in older surveying systems and historical contexts.
Conversions to Other Units
The square perch can be converted into several modern and traditional units of area:
- Square Feet: 1 square perch = 272.25 square feet
- Square Yards: 1 square perch = 30.25 square yards
- Square Meters: 1 square perch ≈ 25.29 square meters
- Acres: 1 acre = 160 square perches
Historical of Square Perch
Depicted on the left side of figure 3 is the square perch, derived from the rod or perch measure, which has its roots in the Roman Empire and were widely used in medieval England. The concept of square perch became to be adopted as small area measures in the farming and housing developments. In many of the British colonies, such as America and Australia, it was fine measure before the coming of the metric and the modern imperial unit systems.
Comparison with the Acre
Use in Land Measurement Today
Although the square perch is largely obsolete in contemporary surveying, it remains in limited use in certain regions and contexts:
- Australia: Still mentioned in rural land measures and older property documents. Historical records and conventional land appraisals occasionally make reference to the United Kingdom and Ireland.
- United States: Infrequently used, although it could be found in historical land survey legal descriptions.
