You can measure a circle pipe to determine its outside diameter by measuring its circumference and using a simple calculation.
Here's how:
-
Measure the Circumference: Wrap a flexible measuring tape snugly around the outside of the pipe. Make sure the tape is straight and not overlapping. Note the measurement in inches or centimeters. This is the circumference.
-
Calculate the Diameter: The diameter of a circle is related to its circumference by the formula:
Circumference = π * Diameter
Where π (pi) is approximately 3.14159.
To find the diameter, rearrange the formula:
Diameter = Circumference / π
Therefore, divide the circumference you measured by pi (approximately 3.14159) to get the outside diameter of the pipe.
Example:
Let's say you measure the circumference of a pipe and find it to be 9.42 inches.
- Diameter = 9.42 inches / 3.14159
- Diameter ≈ 3 inches
Therefore, the outside diameter of the pipe is approximately 3 inches.
Summary:
To measure a circle pipe and determine its outside diameter: measure the circumference using a flexible measuring tape, then divide the circumference by pi (approximately 3.14159). The result is the outside diameter of the pipe.
