and centimeters. It is valuable to both Americans (using the inch system) and those who use the Metric system of measurements. It goes up to 38″ diameter (955 millimeters diameter). The only thing it doesn’t offer is the ability to measure straight objects. You would have to have a regular tape for that.

Who would use this tape? Inspectors who travel and deal with both systems. Any drilling companies that use both metric and imperial systems of measurement.

Pi Day is March 14. This year you can help celebrate by answering the question at the bottom.

Pi is the constant ratio of a circle’s circumference to its diameter, no matter what size the circle is. This is useful knowledge when you work with water pipes or oil or gas pipelines, and you need to replace part of it. You can measure the circumference and divide by pi. But there’s an easier way to do that.

Let a Lufkin Diameter tape measure do it for you. You just wrap it around the pipe, and read the diameter. Mathematicians call pi an irrational number, since it goes on for an infinite number of decimal places, but using a diameter tape is a very rational and easy way to find the diameter of a pipe.

Add A Pipe Diameter Measuring Tape To Your Toolbox

Diameter tape measures are able to give you the diameter of a pipe, pipeline, log, or any other round object. They do it in 1 easy step. All you do is wrap the pipe diameter measuring tape around the pipe and read off the diameter. A regular tape measure would give you the circumference. Then you would have to divide by pi (3.14159). That adds another step, plus you would need a calculator, pencil, and paper to arrive at the diameter.

Why do you need a diameter tape in your toolbox?

  • To measure the diameter of a heater hose in your car, for replacement.
  • To measure the diameter of your round furnace ductwork, so you can extend it, or tap into it.
