Know How to Convert MM to Inches To know how to convert mm to inches may be kind of tricky. There are a few simple ways to do this. One: Understanding These Units of Measurement One way to learn how to convert mm to inches is to remember a few things. You probably are aware that meters can be broken down to centimeters, particularly, a hundred centimeters. These are broken down into 10 millimeters. So, if you would take this in fraction form that would mean there are 1/100th centimeters in a meter, and you would get 1/1000th millimeters equivalent to a meter. Taking that notion in mind, you will see that 25.4 or 25 and 4/10 millimeters would be equivalent to an inch. Bear this in mind. This would show you that the measurement of 2 and 1/2 centimeters is equal to an inch. Sounds confusing? Here is another way to do it. Two: Conversion by Means of a Tape Measure or Ruler Another manner of converting millimeters to inches is by using a ruler or tape measure to check the measurements for length. As aforementioned, the figure 25.4 is important. You use this to divide a millimeter figure by that number. Hereâ€™s how it goes: For example, you have a measurement for the length of around 2,540 mm. You will then have to divide that figure by 25.4. The answer would be 2540mm equivalent to 100 inches. Three: The Simplest Way is to Use a Table or Chart A chart or table showing you certain measurements and their equivalents would also be the easiest way to do conversions. Typically, most people refer to this to help with manual conversion. For a sample on this, here are the conversion units that are equivalent to a millimeter to 8 millimeters. For a millimeter, the inches in decimal would be equal to 0.04. When taken in fractions, the equivalent figure of a millimeter to inches would be 0.63/16. Two millimeters would be equal to 0.08 inches in decimal form, and 1.26/16 inches in fractions. Three millimeters is equal to 0.12 inches (for its decimal form) and 1.89/16 inches (fractions).

Four millimeters, when taken in decimal form for inches would be equivalent to 0.16, and 2.52/16 for its fraction form. For five millimeters, its equivalent in inches for decimal form would be 0.20 and 3.15/16 for its fraction form. Six millimeters would then give you 0.24 inches in decimal form and 3.78/16 in fraction form. When you want to know the equivalent units of measurement for seven millimeters to inches, you would be looking at these figures: Around 0.28 for decimal form and 4.41/16. For eight millimeters, the figures that would come up for inches in decimal form and its fraction form would be 0.31 and 5.04/16, respectively. Taking a look at these three ways can teach you how to convert mm to inches. If you prefer the third way, which is to use a chart, this, by far, would be the simplest manner to understand the figures because you already have something to base it on.
