The difference between 6mm and 1/4 inch is very small in terms of measurement accuracy and precision. 6mm is slightly larger than 1/4 inch, but the difference is minimal and may not be noticeable in most practical applications. Both measurements are precise and accurate for most everyday purposes.

The .22 bullet is smaller than the 9mm in size, (about 6mm) and is lighter in weight.
The main difference between a 6mm and a 6cm is their unit of measurement. The "mm" stands for millimeters, which is a metric unit of length equal to one thousandth of a meter. On the other hand, "cm" stands for centimeters, which is also a metric unit of length but equal to one hundredth of a meter. Therefore, a 6mm is much smaller than a 6cm, as 1 cm is equivalent to 10 mm.
Airsoft bbs are made up of plastic and are 6mm in diameter and are .24 cal, BBs however are metal and are .177 cal (4.5mm)
2.4 mm All kidding aside: the 3.5mm lens has a wider angle than the 6mm one. This means that in a picture, you will see a larger area with the 3.5mm lens, but with the 6mm lens you'd see more (sharper) detail.
6mm is equal to a 2 gauge.
6mm = 6/1 mm.
4mm-6mm in inches = -2
6mm is thicker than 2mm. It has a greater thickness of 4mm.
Well there are 4 6mm beads in an 1", so there would be 64 6mm beads in 16".
For a 6mm hole, a 6mm standard drill bit should be used.
