Solution:The tip of the pencil is at the fifth marking after the 9 cm mark. So, the length of the pencil is 9.5 cm. This is one of the most used tools in your sewing basket. The flexible properties of this ruler makes it perfect for measuring around the body.

In the adoption of the millimetre as the "small" unit of length for metrication (instead of the centimetre) the Metric Conversion Board leaned heavily on experience in the UK and within the ISO, where this decision had already been taken. [20] [21] [ circular reference] Short tapes are very versatile and can be used in the home for DIY and in the construction and engineering industries amongst others. If squinting at the tiny measurement markings on a tape measure isn't your favorite part of using these tools, then you'll appreciate the clearly marked fractions on this tape measure, which are actual numerals, not just lines, indicating 1/8, 1/4, and 1/2 inches. You'll still need to count line markings for 1/16s of an inch, however. We tested both the 16-foot and 25-foot models and found them to be very accurate, comfortable to hold, and quite easy to read. The 1-inch-wide blade is coated with nylon for durability, and the case of the tape measure is very sturdy, with a rubbery coating for easy grip and added protection against damage from drops. The logic of using the millimetre in this context was that the metric system had been so designed that there would exist a multiple or submultiple for every use. Decimal fractions would not have to be used. Since the tolerances on building components and building practice would rarely be less than one millimetre, the millimetre became the sub-unit most appropriate to this industry. The fibreglass blade is extremely resistant to damage from stretching, ripping, excessive heat or water.In this the industry was grateful to the SAA (now Standards Australia) for the early production of the Standard AS 1155-1974 "Metric Units for Use in the Construction Industry", which specified the use of millimetres as the small unit for the metrication upgrade.

The measurements on the bottom of the image given below are in centimeters and millimeters. 10 millimeters make 1 cm, so there are 10 divisions between each centimeter. Each small division is equivalent to 1 mm. When looking at the given image, the first small mark after the 5 cm marking denotes a measurement of 51 mm which can also be referred to as 5.1 cm. Solution:The vase end is at the second marking after the 7-inch mark. So, the length of the vase is 7.2 inches. A tape measure or 'measuring tape' is essentially a type of ruler made up of a long strip (the blade or tape) of fibreglass, plastic, steel or stainless steel marked off with measurements along its length. These measurements can be metric (centimetres & metres) or imperial (inches & feet) or even both .

As for the blade width, around 1 inch is best. Thinner than that, and the blade can be flimsy. Wider, and you may find the tape measure too bulky or difficult to retract. The sale of dual Metric/US Customary scale measuring tapes is slowly becoming common in the United States. For example, in some Walmarts there are Hyper Tough brand tapes available in both US customary units and Metric units. Unlike US rulers, of which an overwhelming majority contain both centimeter and inch scales, tape measures are longer and thus traditionally have had scales in both inches and feet & inches. So, the inclusion of a metric scale requires the measuring device either to contain 3 scales of measurement or the elimination of one of the US Customary scales.A second tape measure design is what is called the long tape. These are cased tape measures with tapes of up to 200 m in length. It is designed for engineers and builders. Long tapes, instead of being returned by a spring, are usually returned by hand crank. Because surveying was usually done in rods, surveyors used long tapes of 2 rods (1.01 m, 33 feet), and 4 rods (2.01 m, 66 feet). Surveyors also used 49 + 1⁄ 2 feet of a 50-foot tape for 3 rods and 99 feet of a 100-foot tape measure for 6 rods Aird, Forbes (1999). Mechanic's guide to precision measuring tools.
