Can you explain the diameter measurements used in bullets, wire and nails?

The ball size is then determined by measuring the ball diameter variation, which is the difference between the largest and smallest diameter measurement.

However, subsequent diameter measurements of a similar extrasolar planet (HD 209458 b), which transited its star, showed that these objects were indeed gas giants.

The existence of Reuleaux polygons shows that diameter measurements alone cannot verify that an object has a circular cross-section.

These graduations are designed to convert circumferential distance into diameter measurement so the observer can read the diameter directly from the scale.

We continued to make the diameter measurements, anyway.

Bore is the diameter measurement of the cylinders in a piston engine.

Electronic surveying instruments such as a total station allows the observer to measure the position of each diameter measurement and the length of the trunk section between each measurement.

One way to check is to take a diameter measurement at an intermediate point and then project what the diameter would be for the chosen model at the point.

Each "spring" was three hundred feet high, each "bell" seven hundred and twenty feet long with an overall diameter measurement of one hundred and twenty feet.
