Or what if you wanted to frame a photo you have? In this case, you might have to measure the picture to see what kind of frame it would fit in. There are two types of rulers you can use: the inch, or imperial, ruler and the centimeter, or metric, ruler. Inches correspond to the imperial system, which is the main measuring system used in the US and a smattering of other countries.
Meanwhile, centimeters are part of the metric system, which is used around the world in both everyday life and science. While we will be providing pictures you can use to follow our instructions, we recommend getting out your own ruler or measuring tape so you can follow along in real time.
Now, notice the lines between each inch, with some longer and some shorter than others. Each of these tiny lines represents a fraction of an inch. There are five different lengths of lines in total. The inch is the biggest unit on a ruler and is represented by the longest line. Each 1-inch line is labeled with a number indicating what inch it is on the ruler as the image above shows. Example: If you were to measure the length of a sheet of computer paper, the piece of paper would come up to the inch mark on your ruler, indicating that it's exactly 11 inches long.
Example: Say you decide to measure the length of a corn on the cob. You find that your ruler comes to the second line after the 6-inch mark. The ruler comes to the seventh line past 3 inches. Knowing how to read a ruler in cm is also helpful for people who'd prefer to not work with fractions which you must do with inches and who'd like to work with other units instead in this case, millimeters.
The standard metric ruler is 30 cm long. Each centimeter is labeled with a number to show the measurement it's referring to. You might see inches on the other side of your metric ruler. In this case, refer to the instructions above to learn how to read a ruler in inches.
Also, be aware that 30 cm does not directly equal 12 inches, even though they are often put on the same ruler! There will always be 10 lines from one centimeter to the next centimeter. In total, there are three different lengths of lines on a metric ruler.
The longest line represents the biggest unit on the ruler: 1 cm. Each centimeter is labeled on the ruler The most common object used to estimate inches is the adult thumb, which is about 1 inch wide. Other options may include a water bottle cap, a detachable pencil eraser, the width of a standard rubber eraser, the length of a paperclip, and the length of a standard small sewing pin.
Place the edge you want to measure on a blank sheet of white paper. Use a pencil to trace the length of the edge from 1 end to the other. After tracing the edge, you can remove it from the paper. Make sure that you use white or light colored paper so that you can clearly see the marks you make. Place the inch-long object at the start of the tracing and mark where it ends. Mark the place on the line where the other end of the measuring object stops with a pencil.
Then, use a pencil to mark on the line immediately above your thumb. Shift the object along the line so that the starting point of the object is placed along the line that previously marked where the top of that object was. As before, make another mark along the line where the top of your object is now located. Each time you shift the position of the measuring object, make sure that the measuring edge lies parallel to the line.
If the space after the last line is significantly smaller than the rest, use your eye to judge how much shorter that line is and estimate what fraction of an inch it represents. After reaching the end of the line, remove the measuring object. Count the number of gaps in between your marks. This number is a rough estimate of the number of inches. Make sure that you count the space before the first line and the space after the last line, as well. Method 3. Convert feet into inches by multiplying the number of feet by There are 12 inches in every 1 foot.
To convert a measurement taken in feet to its equivalent value in inches, you must multiply the value in feet by Calculate inches from yards by multiplying by There are 36 inches in every 1 yard. If you have a measurement taken in yards and you need to know the equivalent number of inches, you would multiply the yard value by Find the number of inches based on the number of miles.
There are 63, inches in every mile. If you are given the length of a distance in miles and need to know how many inches are in that distance, multiply the number of miles by 63, Method 4. Calculate inches from millimeters by multiplying by 0. Every 1 millimeter is equivalent in value to 0. Multiply a length value taken in millimeters by a conversion factor of 0. Convert centimeters into inches by multiplying by 0. There are 0.
To find out how many inches there are when you know a distance measured in centimeters, multiply the centimeter value by a conversion factor of 0. Determine the number of inches from the number of meters. Every meter is equivalent to If a length value has been measured in meters, you can convert it to inches by multiplying that value by a conversion factor of In this case, that distance would be Most rulers are not calibrated in hundredths of an inch.
Not Helpful 5 Helpful 2. To measure anything, you need a measuring device such as a ruler, yardstick, measuring tape, etc. It not only improves the accuracy of the measurement, but also has a scale of inches and centimeters so that it can be used in our work. If you are like us, you need a precise online ruler to measure the product size, i believe this online virtual ruler can also meet your needs.
I am very happy that many people like our online ruler, also i am very excited to review all the comments from all the visitors. This ruler measure in two different units of length, inches on one side English ruler and centimeters on the other side metric ruler.
A metric ruler is use to measure centimeter cm and millimeter mm , the centimeter is a unit of length in the International System of Units; An English ruler provides incremental measurements in inches, with each inch further divided into smaller fractions. Read an English ruler using fractions of an inch. The distance between any two large numbered lines is 1 inch. Observe the much simpler metric rulers. The distance between any two large numbered lines is 1 cm, a metric ruler features two types of lines.
The largest mark centimeters, or cm.
