There are ten millimetres in a centimetre.
The millimetre (international spelling as used by the International Bureau of Weights and Measures SI unit symbol mm) or millimeter (American spelling) is a unit of length in the metric system, equal to one thousandth of a metre, which is the SI base unit of length. There are 10 millimeters for each centimeter. The numbers on the ruler represent centimeters (cm). On a metric ruler, each individual line represents a millimeter (mm). Similarly, what is the definition of metric ruler?Ī metric ruler is the standard instrument for measurement in the scientific laboratory. Inspect the Ruler The first thing you should notice about standard scale rulers is that one side of these measuring tools is designated for feet, with inches on the other size of the zero. Follow these three steps to read customary or metric scale rulers. A metric ruler provides incremental measurements in centimeters, with each centimeter further divided into millimeters. Scale rulers can combine up to four scales or feature a symmetric cross-section with three lobes and six scales. Before you start measuring, make sure that one end of the object is lined up with the 0 cm mark on the ruler.įurthermore, what is a metric and English ruler? An English ruler provides incremental measurements in inches, with each inch further divided into smaller fractions. Each millimeter is one-tenth of a centimeter, so ten millimeters equals one centimeter. The individual lines between the numbers represent millimeters. On a metric ruler, the numbers represent centimeters. There are smaller lines between the larger centimeter lines, which represent millimeters. The distance between them is equal to 1 centimeter. A scale labeled 1/8 translates to 1/8″ = 1′ or 1/96 scale.To read a metric ruler to measure centimeters, look at the long lines on the ruler that are numbered 1-30, which are the centimeter marks. Major divisions of each scale represent feet which are further subdivided into 12ths or 16ths. Determine the number of millimeters by counting the number of lines past that number until you get to the end of the object. What are all of the scales on the architects scale?Ĭommon scales for a triangular architect’s scale are: 16 (full), 3, 1-1/2, 1, 3/4, 1/2, 3/8, 1/4, 1/16, 1/8, 3/32. Determine the number of centimeters by identifying the number just before the end of the object. As an example, a 1/4 inch = 1 foot architect scale will have markings that increase by 1 foot every 1/4 inch a 4 foot wall is represented by a 1-inch length, if measured with a conventional ruler. Lay the proper scale next to the item on the drawing and take the measurement. You just have to use the scales to get a feel for the divisions. The 1, 2, 3, etc are metres, and each small division is 5 mm. On the 1:75 scale, the intermediate is not numbered, but it is there at, again, 500 mm.
On this scale, each small division represents 2 mm, and each longer bar represents 10 mm. This would represent a drawing with a scale of 1/8″ = 1 foot.
For example, 1/8 on the ruler is in fact a scale that converts 1/8 inch on the drawing to 1 foot.
