You can measure the length, width and height of any object by using a measuring device, such as a ruler or tape measure. Laying the object on a flat surface also helps to get more accurate figures.
Know MoreWhether you opt to measure in inches, millimeters or another unit of measurement, it is important to use the same unit for all three measurements.
The measuring device you should use depends on the size and location of the object you are measuring. A ruler can be used for small objects, while a tape measure is preferable for larger ones or objects that are harder to reach.
Note that when you place the object flat on a surface, the height is the dimension from the floor to the topmost part of the object. When measuring the other sides, the length is the longer of the two, and width is the remaining side.
A metric ruler is used to measure the length, height and width of an object or the distance between two points, objects or places. Depending on the length of the metric ruler, it can be divided into millimeters, centimeters, decimeters or meters.
Full Answer >To use a ruler, place it alongside or on top of the object or line that is to be measured and count the number of marks from edge to edge of the object. For those who are working with a metric ruler, the longer lines are denoted by a numerical value and represent centimeters, with ten smaller lines placed in between each centimeter, denoting a millimeter. For those who are working with English rulers, each of the longer lines indicate an inch, with eight smaller lines separating each inch to represent the length of 1/8th of an inch.
Full Answer >Most standard rulers are 30 centimeters long, which makes 1 centimeter equal to one-thirtieth of the length of a standard 12-inch, or 30-centimeter, ruler. The centimeter is a metric unit of measure that, according to Metric-Conversions, is equal to 0.3937 inches.
Full Answer >Measure arm reach using a tape measure. First, stand in front of a wall, and extend one of your arms horizontally in front of you, keeping your fingertips straight. Walk towards the wall until you touch it. Use a tape measure to measure the distance between the armpit and the wall. This is arm reach.
