ISO 965-3:1980 ISO general purpose metric screw threads - Tolerances - Part 3: Deviations for constructional threads Sometimes you can’t find any ISO size on a tyre, only the old-school markings. Although they’re familiar they can be confusing. Tyres of the same size may come with lots of different markings: 28×1¼×15/8, 28×1¾×1¼ or 700×32C, for example, which are all 32-622. How do you know what size tyres will fit your bike? It should be easy: buy exactly the same model of tyre as those already on the bike. Of course, this isn’t much help if identical tyres aren’t readily available, if you fancy something different or if you’re looking for replacements in unusual and hard-to-find sizes. Depending on the number system you are using, leave the scientific notation or convert it into the real number form (decimals). Scientific notation to engineering notation:

Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of 10) can be translated to decimal form using the same principles. Take the fraction 1 In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below. 64 th

In addition to the A-series, there are also the B and C series. The B series extends the range of paper sizes available in the A-series, while the C series is limited to envelopes.

When a is a fraction, this essentially involves exchanging the position of the numerator and the denominator. The reciprocal of the fraction 3 the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 Scientific notation is also referred to as standard form in the UK number system. But in some regions, standard form means the real number form. The ANSI/ASME Y14.1 standard was adopted by the American National Standards Institute in 1995. The various formats available within this standard are represented by ANSI followed by a letter. However, since the introduction of the system, the traditional approach has remained the most commonly employed.Nowadays almost all rims have hooked flanges (required to retain folding tyres) that will hang onto tyres up to three times their width. This increases the cushioning effect: you get more comfort out of the same tyre at the same pressure when you fit it to a narrow rim – yet it still rolls just as easily. Found mostly on mountain bikes and used as a marketing term for wider 622 mm / 700C tires ISO / ETRTO (mm)

Pipe threads where pressure tight joints are made on the threads - Part 1: Taper external threads and parallel internal threads.

Proper fraction button and Improper fraction button work as pair. When you choose the one the other is switched off. Used on mountain bikes, these tires also go by the names: 27.5+, 650+, 6Fattie, or even just "Plus tires". ISO / ETRTO (mm) As the name indicates, the international system is a global scheme that is used across the globe. It is also known as ISO paper. What differentiates the international system from its North American counterpart is that it encompasses a format that has an aspect ratio equal to the square root of two (1.414). As such, it is a convenient system that makes it easy to change the size or format of a document from printing in an alternative ISO size or format. The most commonly used series within the ISO standard is the A-series, of which the A4 format is particularly popular. All paper sizes within the A-series have a name that starts with A followed by a number. The smaller the number, the larger the paper. An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers. Multiples of 2: 2, 4, 6, 8 10, 12
