7.5 mm is the equivalent to 0.29527559055 inches, this would typically be rounded to 0.3 in.

7.5 mm equals 0.75 cm. A 7.5 mm measurement is often used on rifle rounds and various electrical components and is a very common measurement used. One centimetre is equivalent to around 0.39 inches. 1 inch is equivalent to 2.54 centimetres.

The 7.5mm measurement is also found in jewellery, particularly in pearls and necklaces. The most common size for round pearls is 7 to 7.5 mm. In science, the Ka-band section of the electromagnetic spectrum measures from 7.5 mm to 9.2 mm. These measurements have been used in laboratory experiments to test the Ka-band opacity of phosphine and ammonia under simulated conditions in a bid to recreate the encounter between Cassini space probe and Saturn in space.

7.5mm is also a measurement used in making camera lenses and their respective focussing capabilities,  in particular for fisheye lenses. The 7.5 mm fisheye was once called the full sky lens. It was primarily used for astrophotography and astronomical observations. Today the fisheye lens is widely used by professional photographers or researchers when special effects are desired. Looking through a fisheye lens, you can see everything from the ground at your feet, to the sky overhead and virtually everything to your left and right within a radius of 180 degrees.

7.5 mm is equivalent to 0.02 feet rounded to the nearest two decimal places. 7.5 mm is also equivalent to 0.0075 metres. 7.5mm also represents one hundredth of a wavelength on a 400 MHz frequency.

I converted 7.5 mm to cm and I got 0.75 cm.

Then I converted cm to inches. And I got 0.2952755906 in.

I inch is equal to 2.54 cm.

Hope this helps.
