Perfect Tool for Precision – A Must-Have for Any Toolbox!
This Perfect Pi Diameter Circumference Tape Measure is an absolute game-changer for anyone needing precise diameter and circumference measurements! Whether you're working with pipes, trees, or any cylindrical objects, this tool makes it quick, easy, and incredibly accurate. The tape is designed specifically for measuring diameter and circumference effortlessly, eliminating the need for manual calculations. The markings are clear, easy to read, and extremely accurate. it works great everytime, I am a wood worker myself and this thing will solve some real life challenges. One thing to keep in mind: the diameter side follows a unique scale to compensate for the mathematical formula that converts circumference to diameter. Don’t mistake the standard with imperial scale—it’s designed this way for precision, where the smaller scale is imperial and the larger scale is meteric. The tape itself is flexible yet sturdy, ensuring it holds up well over time. Perfect for professionals and DIYers alike! Outstanding Customer Support! – The company stands 100% behind their product. I had a quick question, and their customer service was unbelievably responsive, friendly, and helpful. It’s rare to find such great support these days! This is a family owned business and they stand by their 100% Satisfaction Guarantee If you're looking for a top-quality measuring tool with fantastic customer service, look no further! This is the best circumference/diameter tape measure out there. Highly recommended!

Quality, function and value are all included.
I would give this product a 4-1/2 stars if this was possible in the rating system. I like it very much, but not enough to say that I love it. I was looking for a quality tape measure that provided both inch & metric measurements and was not too large. This product also provides a diameter conversion measurement (when you measure the circumference/perimeter of a round object), which is a definitely a valuable capability. The quality, materials & finish are quite good and are somewhat better than I expected at this price point; this product should last a long time under moderate use. The 1/2" wide (12 foot/3.65 meter) steel tape is very strong/robust. The measurement/marking lines and numbers are very clear/easy to distinguish (high contrast). The tape measure size/storage footprint is just right for my needs; not nearly as bulky as some alternatives but large enough to get a good handle on. The spring loaded, tape retraction action is smooth & fast. The only reason for not rating this a five star product; it has a rectangular ring end on the tape versus a 90 degree bent metal end catch. This requires two hands for the type of measurements that I make most of the time. However, this is a fundamental trade off; it will work better under some measuring conditions. They should probably provide an optional 90 degree bent metal end catch version or clip on. Also, it does not have a lock on the tape; you have to effectively "lock it" with your fingers. This is not a large disadvantage, but I would pay more for this function because it can free up a hand under certain measurement scenarios. This product is highly recommended. It should be noted that I was motivated to post a review of this product because I would receive a free "silicone snap ruler" from the vendor. However, I stand by my review as an authentic reflection of my assessment of the product.

Great tape measure
At first I couldn’t figure out why the inches and centimeters were so long on the Diameter side of the tape. Then it finally dawned on me that it was telling me what the diameter would be when measuring the circumference of an object. I’m a little slow sometimes lol.

A great product for making a perfect cut on a pipe or any cylindrical object

Es una cinta flexible y con material duradero, veo complicado (salvo por desgaste natural) el que se borren las mediciones.

This is by far the best diameter tape I've used for measuring trees. 12' is extremely convenient for large, mature trees with big DBH, I haven't yet met an urban tree that has outsized this diameter tape. The case is extremely durable, and the blade is flexible yet durable (doesn't kink), and the markings are easy to read. I do find the numbers and markings wear off after a while and wish they were more friction resistant. The price is fantastic, though. Overall, this is definitely my tape of choice.
