Reading Centimeters and Millimeters: A centimeter is smaller than an inch. The long hash marks under which numbers are written on the ruler denote centimeters. A millimeter is even smaller than a centimeter.
What is smaller than an inch?
The inch is traditionally the smallest whole unit of length measurement in the imperial system, with measurements smaller than an inch being stated using the fractions 1/2, 1/4 , 1/8, 1/16, 1/32 and 1/64 of an inch.
What are the smaller lines on a ruler?
The larger lines with numbers are centimeters, and the smallest lines are millimeters. Since millimeters are 1/10th of a centimeter, if you measure 7 marks after a centimeter, it is 1.7 centimeters long. English rulers, are much more difficult to read.
What’s in between inches on a ruler?
The 1/2-inch line is located midway between every inch on a ruler. The midpoint between 7 and 8 inches, for instance, would be 7 1/2 (or 7.5) inches.
What is the smallest fraction of an inch on a ruler?
Ruler Scales: 16ths Scale: Each inch is divided into 16 parts and the smallest division is 1/16 of an inch. All fractions must have a denominator of 16, 8, 4 or 2. THE NUMBER FOR WHOLE INCHES APPEARS TO THE LEFT OF ITS MARK.
Which is the smallest measurement?
The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10–35 m across.
What’s smaller than a half inch?
The largest division, 1/2″, has the longest line. The lines at each rank get shorter, ie: 1/4 is shorter than 1/2; 1/8 is shorter than 1/4; and 1/16 is shorter than 1/8. Fractions have two parts, the numerator and the denominator.
Are the small lines on a ruler mm?
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 12. The other side of the ruler will have markings for cm and mm measurement. The small lines between the larger, numbered lines represent millimeters.
How wide is 2 inches?
Did you know? 2 inches is equal to 5.08 centimeters or 50.8 millimeters.
What do the smallest lines on the metric ruler represent?
Reading a Metric Ruler On a metric ruler, the numbers represent centimeters. The individual lines between the numbers represent millimeters. Each millimeter is one-tenth of a centimeter, so ten millimeters equals one centimeter. This will tell you how many tenths of a centimeter (or millimeters) you have.
How long is a standard ruler in inches?
A standard ruler is 12-inches long and 30 centimeters in length.
What measurement is taken four inches from the waist?

What is the smallest fraction?
1/2 has the smallest denominator. We’ve re-arranged the fractions from the least to the greatest. 1/6 is the smallest, and 1/2 is the greatest. 1/4 is placed in between the two.
What is a fractional inch?
A inch is fractioned in two halves that, in its turn, also are divided in its halves and so on successively. This is the progression that the division of fractions of inch results: 1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/128 , where each new term represents half of the previous one. (.
What is smaller than a nanometer?
Scientists often measure lengths even smaller than a nanometer—the width of an atom, for instance, or the wavelength of a light ray. For this purpose, they use the angstrom (Å or A), equal to 0.1 nanometers.
What is the smallest measurement on a tape measure?
The smallest marks on a tape indicate one millimeter or 1/10th of a centimeter. The large, bold markings on a metric tape measure indicate centimeters. The long mark in the center indicates a half-centimeter. To read a metric measuring tape, find the nearest whole centimeter to the end point.
What is smaller than a millimeter?
Micrometer A micrometer (also called a micron) is 1000 times smaller than a millimeter. 1 millimeter (mm) = 1000 micrometers (μm). 4. Nanometer A nanometer is 1000 times smaller than a micrometer.
Is feet smaller than inches?
Since a foot is longer than an inch, this means the answer would be greater than . Find the conversion factor that compares inches and feet, with “inches” in the numerator, and multiply. There are 42 inches in feet.
What is bigger than an inch?
