What Is This Tool?
This converter transforms area values from circular inches, which measure the area of circles with a one-inch diameter, into square inches, the standard unit for planar surface area.
How to Use This Tool?
- Enter the area value in circular inches you want to convert.
- Choose circular inch as the input unit and square inch as the output unit.
- Click the convert button to get the corresponding area in square inches.
Key Features
- Converts circular inch to square inch accurately using the defined conversion rate.
- Browser-based tool requiring no installation or advanced knowledge.
- Supports engineering and manufacturing area calculations related to round objects.
Examples
- 2 Circular inches equals 1.5707963268 Square inches after conversion.
- 5 Circular inches equals 3.926990817 Square inches after conversion.
Common Use Cases
- Determining cross-sectional area of round electrical conductors when diameters are given in inches.
- Calculating areas of rods, shafts, or pipes in mechanical engineering.
- Converting between circular mils and square inches for industry specifications.
Tips & Best Practices

- Not suitable for objects with non-circular shapes or other standard area units.
- Precision depends on the accuracy of π used in the conversion.
Frequently Asked Questions
- What is a circular inch used for?
- A circular inch measures the area of a circle with one inch diameter, often used for cross-sectional areas of round objects like electrical conductors.
- How do I convert circular inch to square inch?
- Multiply the number of circular inches by approximately 0.785398 to get the equivalent area in square inches.
- Can I use this conversion for non-circular objects?
- No, this conversion applies only to circular cross-sections and is not suitable for other shapes.
Key Terminology
- Circular Inch
- The area of a circle whose diameter is one inch, equal to π/4 square inches.
- Square Inch [in²]
- A unit of area representing a square with one inch sides, used in the Imperial/US customary system.
- Cross-Sectional Area
- The area of a cut section of a three-dimensional object, used here for round shapes defined by diameter.
