On a metric ruler, each individual line represents a millimeter (mm). The numbers on the ruler represent centimeters (cm). There are 10 millimeters for each centimeter.
1mm = just over 1/32 inch. 2mm = just over 1/16 inch. 3mm = almost 1/8 inch.
About Inches
Also, 1 inch to mm is 25.4, while 1 inch to cm is 2.54.
A measure of length in the metric system. A millimeter is one thousandth of a meter. There are 25 millimeters in an inch.

Millimeter Measurement
- Place the left end of the object on the 0 mark of the ruler.
- Count the spaces (not the lines) from the 0 to the end of the object or just before the end of the object.
Also shown is a 2-centimeter (cm) ruler that shows 10 mm is equal to 1 cm.
There are no half-size options in European shoes, but in the US and UK, the half-size difference is about ⅛” or 4.23 mm.
How wide is a 6mm ring? An 6mm ring is as about the width of three nickles stacked together. A standard U.S uses nickle measures 1/16 of an inch, which is almost 2mm wide. Three nickles, or 6mm, would measure 6/16 inch.
Millimeter is the SI unit (International system of units) in the metric system. It is used to represent the length of an object or a person. One millimeter is equal to 0.1 centimeter. The symbol of millimeters is 'mm'.
What is about 1 mm long?
A millimeter is about the thickness of a plastic id card (or credit card). Or about the thickness of 10 sheets of paper on top of each other. This is a very small measurement!
Actually, there are 10 millimeters for every centimeter. Now, it is easy to see that the centimeter is larger than the millimeter.

It is typically used to distinguish smaller-caliber weapons, commonly called "guns", from larger-caliber "cannons" (e.g. machine gun vs. autocannon). All 20 mm cartridges have an outside projectile (bullet) diameter and barrel bore diameter of 0.787 inches (20.0 mm).
Millimeters (mm) | Inches (") (decimal) | Inches (") (fraction) |
---|---|---|
5 mm | 0.1969 ″ | 13/64 ″ |
6 mm | 0.2362 ″ | 15/64 ″ |
7 mm | 0.2756 ″ | 9/32 ″ |
8 mm | 0.3150 ″ | 5/16 ″ |
1 inch = 25.4 millimeters. 1 inch = 2.54 centimeters. 1 centimeter = 10 millimeters. 100 centimeters = 1 meter.
Since an inch is officially defined as exactly 25.4 millimetres, a millimetre is equal to exactly 5⁄127 (≈ 0.03937) of an inch.
Therefore, 25 millimeters is approximately equal to 0.9843 inches.
Millimeter - screen ruler app for Android
Millimeter is a simple free screen ruler app. You can measure small objects that fit device screen with this ruler. There are NO ADs in the app for best experience and real full screen measurements.
The inches thickness unit number 0.039 in converts to 1 mm, one millimeter thickness. It is the EQUAL dimension value of 1 millimeter thickness but in the inches thickness dimension unit alternative.
Millimeter A millimeter is 10 times smaller than a centimeter. The distance between the smaller lines (without numbers) is 1 millimeter. 1 centimeter = 10 mm.

While both have the meter as their base unit, the centimeter is ten times larger than a millimeter. 4.
However, one cm is equal to 10 mm.
In short, 1 centimetre = 0.01 meter = 10 millimeter = 0.3937 inches. The relationship between inch and cm is that one inch is exactly equal to 2.54 cm in the metric system.
For threads and PVC Pipe: half inch refers to 15mm, three quarter inch refers to 20mm, one inch refers to 25mm, one and a quarter inch refers to 32mm, one and a half inch refers to 40mm, two inch refers to 50mm.
One millimeter is equal to 0.1 centimeter. The symbol of millimeters is 'mm'. Centimeter is also the SI unit in the metric system.
The distance between numbered marks on that side will be shorter than on the inches side, and the numbered marks will go as high as 30, because there are approximately 30 centimeters in 12 inches (the length of the standard ruler). The small lines between the larger, numbered lines represent millimeters.
Inch [in] | Millimeter [mm] |
---|---|
2 in | 50.8 mm |
3 in | 76.2 mm |
5 in | 127 mm |
10 in | 254 mm |
Where is 5 mm on a ruler?
Look at the unmarked lines on a metric ruler.
The medium-sized line at the halfway point between each numbered centimeter measurement represents half a centimeter, or 5 millimeters.
MM | Approximate Size In Inches | Exact Size In Inches |
---|---|---|
14mm | 9/16 Inch | 0.55118 Inches |
