It's a good idea to check the products size, before we buying it from internet, try this virtual actural size ruler One centimeter is approximately three times smaller than an inch. Another way to imagine the size of a centimeter is in relation to inches. Most Fractional Rulers are based on the English measuring system where scales are graduated in units of one inch and fractions of an inch.Ī centimeter is 10 millimeters, or approximately the width of a fingernail. Convert Decimals to Fractions with 1/100,000 precision. Decimal Rulers have graduations or marks which are based on the decimal system such as 0.5, 0.25, 0.1, 0.05, etc. The Decimal to Fraction Converter is very simple to use. Fractional Rulers have graduations or marks based on fractions, for example 1/2", 1/4" 1/8", 1/16", etc. There are two types of scales commonly used on rulers Fractional and Decimal. 1 meter = 100 centimeters = 1,000 millimeters.Set the pixels per inch (PPI) according your own device. If you would like to have the online ruler in actual size, So i set the default pixels per inch(PPI) is 100.7 for myself. I found the markings are not very accurate at 30cm, I google the PPI reference and found 100 PPI to my screen,Īfter i measure the size of virtual ruler by a actual ruler, The diagonal screen is 15.6"(inches) of my laptop computer, resolution is 1366x768 pixels. Use 1/8" graduations, 10cm = 4" Use 1/16" graduations, 10cm = 3 15/16" Īdjusting this online ruler to actual size.Ready?

5 If you need to learn how to do that division, let us know. You also could write it this way: "2 goes into 1", etc. But in math this (1/2) thing REALLY is: one divided by two. It looks like "one half" because that's what we call 1/2. Here is an example you already know: Change 1/2 into a decimal. To convert the decimal 0.313 to a fraction, just follow these steps: Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. This equivalence, or conversion factor, is something to memorize once and then use for the rest of your joyful life! The easiest one is this: 1 inch=2.54 cm.Īnd fourth: you need to know how to go back and forth between a decimal (which often is not an exact number) and a fraction (which is perfectly precise). "Equivalent" means a different name for the exact same thing. Third, you need to know just one measurement that is exactly equivalent between a metric distance unit of measure (like a meter, or centimeter, or millimeter) and its equivalent old-fashioned unit of measure. They are easy to learn in about 15 minutes, and we can help with that if you need to learn it.
This means you need to know your times tables. Second, how to do the arithmetic involved in simple fractions. It is 1/1000 of a meter (milli means a thousandth). You need to know 4 things to solve any problem like this:įirst, what a millimeter is, expressed as a fraction of a meter. The reason your teacher says to express your answer as a fraction is so you will work the problem by hand, not use a calculator! Hi, If I understand correctly, you wish to convert 16mm to inches, expressed as a fraction of an inch using proper fractions, not decimals. Next, given that you have x decimal places, multiply numerator and. First, count how many places are to the right of the decimal. Step 2: Remove the decimal places by multiplication.
Re: Converting mm to fractions of an inch Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).
