Most people don’t know what a Diameter Tape Measure is. That’s because most
people never need one. But, here’s a list of users of this special tape. How many users do you know? You probably know most of them:
- plumbers
- oil pipeline workers
- arborists
- auto mechanics
- boat mechanics
- gas line workers
- ball manufacturers
- machinists
- hvac installers
- foresters
- builders
- carpenters
How do they use one?
They wrap the diameter tape measure around the pipe or tree, and simply read the measurement. The scale is marked to give you the diameter, even though it is wrapped around the circumference. That’s because the diameter scale is stretched out by a factor of pi (3.14159). That’s how this special tape makes life simpler for all these users. The workers don’t have to use a regular tape measure and divide by pi.
