# How do you measure the diameter of a tap?

The easiest way to find out the size of the thread in your mixer tap or faucet is to remove the aerator (this is the part that screws off at the end of your tap) and measure the diameter (across the centre) of the thread.

Also, how do I know what size my tap is?

I quickly calculate proper tap-drill diameters using this simple formula. Tap-drill diameter equals nominal diameter minus thread pitch. For example, drill size for a 3/8-16 thread is 0.375 0.0625 (pitch) = 0.312 in. in diameter, and for a 10-32 thread, the drill diameter is 0.190 0.032 = 0.159 in.

Also Know, how do you measure the diameter of a bowl? Run your tape measure from rim to rim across the widest part of the top of the bowl or plate. Some typical diameters for different kinds of dishes include: Dinner plates -- 9 inch to 11 inch -- beware the 12-inch plate; it may not fit in your cabinet or dishwasher.

Correspondingly, how do you measure diameter tool?

Slide Calipers: A tool used to measure the inside and outside distance (diameter) and depth of a feature. Different models exist such as digital, dial and vernier calipers. Measurement accuracy of a slide caliper generally ranges from +/- 0.001 inch to +/- 0.0015 inch (+/- 0.02 mm to +/- 0.04 mm).

How do you determine your fitting size?

Measure the Outside Diameter (OD) of your pipe or pipe fitting:

1. Wrap a string around the pipe.
2. Mark the point where the string touches together.
3. Use a ruler or measuring tape to find the length between the tip of the string and the mark you made (circumference)
4. Divide the circumference by 3.14159.
