A ruler or measuring tape can be used to measure lengths in both metric and customary units. Here, the ruler is marked in centimeters (cms) along the top and in inches along the bottom. The marks or intervals on a ruler are called hash marks.
What are the little marks on an inch ruler?
The markings on a standard ruler represent the fractions of an inch. The markings on a ruler from the start to the 1″ mark are: 1⁄16“, 1⁄8“, 3⁄16“, 1⁄4“, 5⁄16“, 3⁄8“, 7⁄16“, 1⁄2“, 9⁄16“, 5⁄8“, 11⁄16“, 3⁄4“, 13⁄16“, 7⁄8“, 15⁄16“, and 1”.
What do the lines on a ruler stand for?
Each of these tiny lines represents a fraction of an inch. There are five different lengths of lines in total. Each inch is divided into 16 lines, meaning that the space between each line is 1/16 inch long—this is the smallest length you can measure with a ruler.
What are the markings on a tape measure?
On every tape measure, there are both small and large tick marks and sometimes numbers. The biggest tick mark usually denotes inches, the second biggest denotes 1/2 inches, and so on. The largest numbers correspond to inches, with fractions of inches being in between each of the largest numbers.
Can you call a ruler a scale?
In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale. A device for drawing straight lines is a straight edge or ruler. In common usage, both are referred to as a ruler.
What are the lines on a graduated cylinder called?
This curve is called the meniscus. Always read the measurement at the bottom of the meniscus. The graduated cylinder will usually have heavy markings at 10, 20, 30 . . . milliliters.
Where are the centimeters on a ruler?
The metric side of the ruler has centimeter numbers from 1 on the far left up to 30 on the far right. The final metric point on the ruler is 30.5, making the ruler 30.5 cm long. The longest lines at each centimeter number indicate the centimeters along the edge of the ruler.
Where do you start measuring on a ruler?
It is important to measure objects using the measurement lines on the ruler. We always start from the ‘0’ line on the ruler and we line our objects up with this point. A common mistake when learning to measure objects with a ruler is to not line up the object with the zero correctly.
Where is millimeters on a ruler?
Look at the unmarked lines on a metric ruler. There are 2 separate units of measurements on a standard metric ruler—centimeters and millimeters. The numbered lines correspond to centimeters, while the unmarked lines indicate millimeters. If you look closely, you’ll notice that there are 10 millimeters in a centimeter.
Where is the 3/8 mark on a ruler?
The very first line on the left hand side of the ruler is the 1/16 of an inch mark. Between 0 and 1 inch, there are marks that denote 1/16, 2/16 (or 1/8), 3/16, 4/16 (or 1/4), 5/16, 6/16 (or 3/8), 7/16, 8/16 (or 1/2), 9/16, 10/16 (or 5/8), 11/16, 12/16 (3/4), 13/16, 14/16 (or 7/8), 15/16, 16/16 (or 1) of an inch.
What is the diamond mark on a tape measure?
The black diamonds which appear every 19 3/16” on metal tape measures are for spacing I-beam “timbers.” Several wood-product manufacturers offer I-beam “timbers” as a substitute for solid lumber floor joists. The diamond marks on tape rule blades are for spacing these engineered floor joists in new construction.
Why ruler is called ruler?
If you’re a queen, a sultan, or a czar, you’re a ruler. Besides “person who rules or governs,” you can define ruler as a measuring device that’s marked with inches or centimeters. Both meanings stem from the verb rule, “to exercise power” or “to control,” which came to also mean “mark with lines” in the 1590s.
What is the scale of a ruler?
Measuring with a Scale Ruler Common scales are 1/2, 1/4 and 1/16. These reflect the fractions of an inch that correspond to feet in the full-scale dimensions. To read a blueprint with a scale ruler once the appropriate scale is determined, line up the zero mark with the beginning of the length to be measured.
What are the different types of rulers?
Types of Measuring Rulers Desk Ruler. The best-known and most common type of ruler, desk rulers are generally used for measuring, drawing straight lines and as guides when cutting with blades. Protractor. Used to measure angles or circles, protractors are clear, circular or half-circular rulers. Adjustable Triangle.
What are the markings on a graduated cylinder?
On each of the 100mL and 250 mL graduated cylinders there are markings (graduations) that indicate the volumes along the length of the cylinder. Notice there are two sets of graduations on each cylinder, a graduation for larger volumes and smaller volumes.
What does a metric ruler measure?
A metric ruler is used to measure length. It is divided into units of centimeters. Each number on the ruler represents 1 centimeter.
Are mm and CM the same on a ruler?
On a metric ruler, each individual line represents a millimeter (mm). The numbers on the ruler represent centimeters (cm). There are 10 millimeters for each centimeter.
What does a scale measure?
Scales measure weight, which is the force acting on a mass that is equal to the object’s mass times its acceleration due to gravity. A scale can’t measure mass directly, because the weighing mechanism and the weight of any given object are dependent on local gravity.
