Cells are typically measured in micrometers
The diameter is measured using a tape measure.
Diameter.
In the US its diameter is measured in inches.
A diameter is measured by using a ruler. However, you also could use a digital caliper to measure the diameter of a circle.
Tube is measured by outside diameter, pipe is measured by inside diameter.
The diameter of the bullet casing, measured at 7.3 mm, is 7.3 millimeters.

The APT (anterior-posterior to transverse) diameter ratio of the thoracic cage is measured by comparing the anteroposterior (AP) diameter to the transverse (width) diameter of the chest. This is typically done using imaging techniques like chest X-rays or CT scans, where the AP diameter is measured from the sternum to the spine, and the transverse diameter is measured at the widest part of the thorax. The ratio is then calculated by dividing the AP diameter by the transverse diameter to assess the shape and potential abnormalities of the thoracic cage.
When carefully measured, it's found to be precisely 30.2 .
The true diameter of the cell can be calculated by dividing the diameter of the cell in the photo by the magnification. In this case, if the cell in the photo is 2 millimeters in diameter and is magnified 40 times, the true diameter of the cell is 2 mm / 40 = 0.05 mm = 50 micrometers.
Wire diameter is measured in millimetres (mm)
the cell of bacteria.
