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] 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 .

The first commercialized Digital Tape Measure was released by Starrett in 1995 under the DigiTape brand. In March 2022, REEKON Tools announced the T1 Tomahawk Digital Tape Measure which featured significant accuracy improvements over previous attempts. [12] Design [ edit ] The building industry was the first major industry grouping in Australia to complete its change to metric, being completed by January 1976. [19] Australian 5 Metre measuring tape, with the markings entirely in millimetres. 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. 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. Some tape measures have a magnetic hook, which is useful when measuring steel or other magnetic metal items but can potentially be a nuisance, as the magnet can attach itself to various nearby metal items other than what you want to measure. The DEWALT Tough Series has a removable magnetic tip, so you can take it off when not needed.The metric units for linear measurement in building and construction will be the metre (m) and the millimetre (mm), with the kilometre (km) being used where required. This will apply to all sectors of the industry, and the centimetre (cm) shall not be used. … the centimetre should not be used in any calculation and it should never be written down". [22] Cased tape measures are the most familiar type, and the type we tested at our lab. These tape measures have a retractable blade marked with imperial or metric measurements, and a case that’s made of plastic or metal. This type of tape measure is a must-have in your toolkit and is useful for most measuring tasks around the home.The Irwin Strait-Line is a top option for any tool collection.

Fibreglass long tapes, however, usually come in an 'open reel' design where the blade is wound around a reel held together by an open frame. Closed Reel Tape Measures – Advantages With the mass production of the integrated circuit (IC) the tape measure has also entered into the digital age with the digital tape measure. Some incorporate a digital screen to give measurement readouts in multiple formats. An early patent for this type of measure was published in 1977.
