What does a PI tape measure?
Pi Tape Measure gives a quick direct single reading of average diameter with micrometer accuracy simply by placing tape around the periphery. It is used to measure round or out-of-round specimens of concrete, soils, and asphalt.
How accurate is a PI tape?
Pi Tape metric tapes have a diameter accuracy of ± 0,03 mm up to 3 600 millimeters. Pi Tape inch tapes have a diameter accuracy of ± 0,001″ up to 144 inches. In addition, Pi Tape can construct measuring tapes with customized lengths and widths to meet your every need.

What is the least count of pi tape?
What is the least count of measuring tape?
1mm
Usually the Least count of a Measuring tape is 1mm and 1/16 inch.
How do you read a diameter scale?
The inches in diameter by 64ths scale is designed specifically for measuring diameters such as pipes. When you hold the tape around a pipe at the line which is ~1.5″ from the hook (on the backside of the blade), then measure where it overlaps. That point is the diameter.
How do you calculate the least count on a tape measure?
Thus the measuring tapes can accurately measure 1/10 of an inch or 1 / 16 of an inch or 1/10 of a centimeter., which is the same as 1 millimeter. Depending on whether you use the tape to measure in inches or centimeters , the least count would be 1 / 10 of an inch or 1/ 16 of an inch or 1 millimeter ..
How do you convert cm to diameter?
Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter, 3.18 centimeters.
How do you find the diameter of a tape measure?
Measure just the radius of the circle if it is very large. The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter.
What is the value of diameter?
If the circumference of a circle is known then we can easily find the value of the diameter by substituting the values in the formula: Diameter = C ÷ π; where ‘C’ is the circumference and the value of π is 22/7 or 3.14 approximately.
What does inches of DIA by 64 ths mean?
How to read a pi tape?
Wrap the tape around the object to be measured. The vernier scale should be just below the gage member. Tighten the tape around the object with 5 pounds tension for O.D. tapes (For I.D. tapes, use 0 pounds tension). Locate the “zero” on the vernier scale and note the highest value achieved on the gage member above it

What things to know to read a tape measure?
– When reading a tape measure, find the closest whole inch to the end point. Then examine leftover indicator lines to see what fractions of an inch remain. – To read an inch, look for the large numbers. That number is usually in bold, black type. – To read 1/2-inch measurements, locate the second-longest mark between the longer inch marks.
How to use Pi tape?
when calibrating a PI tape on a flat horizontal surface. OD PI tapes are referenced to 20 °C with 2.25 kg (5 lb) tension (within ± 0.5 percent of the load, i.e., Class F mass standards are more than adequate.) applied. There is concern about the proper tension to apply to an ID PI tape since they are normally used under some degree of compression.
