Some pocket tape measures feature a case with a known length (e.g. Be sure to use the hook properly when using your tape measure! Not only does this keep the blade in place whilst measuring, it also guarantees an accurate measurement by compensating for the thickness of the metal hook in the measurement. When taking external measurements, however, the hook can be placed around/behind the object and pulled gently towards the measurer. skirting board) providing an accurate measurement. from the inside edge of an object such as between one internal wall and another) the hook can be pushed against the object (e.g. Some people mistakenly think of this as a manufacturing defect but this is not the case. In other words it moves in and out ever so slightly. You will normally find (on any pocket tape of quality) that the hook 'floats'. In pocket tapes (as seen in the image below), this is usually a straight piece of metal attached to the blade by a number of rivets. The hook or 'tang' of the tape measure is the small, usually metallic component at the end of the blade. 1 inch = 16 x 1/16th of an inch, 8 x 1/8th of an inch, 4 x 1/4 of an inch or 2 x 1/2 of an inch.Each inch will then have eight 1/8th of an inch and sixteen 1/16th of an inch marks. Even smaller marks then denote 1/8ths and 1/16ths (marked in red) of an inch.Ī 16ft tape measure, for example, will have sixteen one-foot marks along its length and 192 one-inch marks (12 inches per foot). The mark directly in the middle of the inch denotes a measurment of 1/2" whilst the markings either side of it represent measurements of 1/4" and 3/4" respectively. Between those numbers are a series of shorter marks which represent fractions of an inch. These numbers sit next to long vertical marks which represent whole inches. When referring to the diagram above you'll see a series of large numbers marked 1, 2, 3, and 4. Most manufacturers have, therefore, opted to produce UK-spec tape measures with both metric and imperial graduations. Despite this almost all 21st Century technical, engineering or construction measurements are quoted in millimetres. We measure our height in feet and inches, our weight in stones and pounds and our speed in miles per hour. Whilst Britain now officially operates a metric system of measurement, our nation still sees a curious mix of both metric and imperial measurements being used on a day to day basis. 41mm can also be referred to as 4.1cm (0.041m) but the majority of trades in the UK do tend to quote measurements in milimetres. The next small mark in line would be 42mm, the next would be 43mm and so on. When looking at the image above, the 1st small mark after the 4cm point denotes a measurement of 41mm. Also, whilst a few tapes show '1m' to display the 1 metre mark, the majority will show '100cm'. Whilst the centimetres are clearly numbered, to make the blade easier to read the millimetres are not numbered. There are 10mm in each centimetre (shown by the ten spaces between each cm) and 100cm in each metre. In other words they're in centimetres and milimetres. The measurements towards the bottom of the image are metric. In response to our customers, therefore, we’ve put together this simple guide that explains just that!Ībove you'll see a picture of a metric/imperial pocket tape measure. We regularly get asked the question “how do you read a tape measure”.
