Where is 7.3 on a ruler

A ruler is a device with measurement markings on it used for measuring drawing straight lines. Students, engineers, contractors, and makers use rulers for math, construction, architecture, sewing, landscaping, and more.

According to Dictionary. Several types of rulers include wooden or metal rulers, yardsticks, seamstress tapes, tape measures , carpenters rules, and architects scales. Rulers have measurements in imperial and metric, imperial-only, or metric-only.

Take the remaining portion of the decimal and multiply it by the fraction increment desired. In this example,. Round the value from step 2 to the nearest whole number. For this example, This value is the numerator of the fractional inch over Add the whole number from step 1 to the fraction in step 3. Bryan Clark has been a freelance writer since If a ruler has no legend the smallest graduation of an inch will have to be calculated. Simply count the number of spaces between graduations or marks contained within a single inch.

We discuss here, Decimal Rulers based on the English measurement system of Inches. If there are numbers on just one side of the ruler, they almost definitely show US customary measures: inches and feet. If the ruler has measurements down both sides, one side will show US customary measures; look for the side where the larger marks inches are numbered up to The other side of the ruler will have markings for cm and mm measurement.

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. Now that you've identified which side of the ruler has metric measurements, line that side of the ruler up with the object you're measuring.

The "zero" line on the ruler usually doesn't line up exactly with the edge of the ruler, so make sure you put that zero line even with one edge of what you're measuring.

Millimeters are usually used to measure very small things. If you're measuring a very small object, it may be easier to bring the object to the ruler instead of the other way around. Now that the "zero" mark on your ruler is lined up with one edge of the object you're measuring, read along the ruler until you reach the far edge of the object being measured.

Because the marks on a mm ruler are quite small and aren't numbered, it may help to put your finger, or the point of a pen or pencil, down to help you keep your eye on the correct mark.
