The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters. It is commonly abbreviated as Fr but may also be abbreviated as Fg , FR or F , and less frequently as CH or Ch (referencing its inventor, Charrière ).
The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
‡ In Canada, a cup was historically 8 imperial fluid ounces (227 mL) but could also refer to 10 imperial fl oz (284 mL), as in Britain, and even a metric cup of 250 mL. Serving sizes on nutrition labelling on food packages in Canada employ the metric cup of 250 mL, with nutrition labelling in the US using a cup of 240 mL, based on the US ...
The conversion between different SI units for one and the same physical quantity is always through a power of ten. This is why the SI (and metric systems more generally) are called decimal systems of measurement units. [10] The grouping formed by a prefix symbol attached to a unit symbol (e.g. ' km ', ' cm ') constitutes a new inseparable unit ...
The traditional Burmese units of measurement were a system of measurement used in Myanmar. [ citation needed ] Myanmar was one of three countries that had not adopted the International System of Units (SI) metric system as their official system of weights and measures according to the 2010 CIA Factbook.

Each variant of the metric system has a degree of coherence—the derived units are directly related to the base units without the need for intermediate conversion factors. [18] For example, in a coherent system the units of force , energy , and power are chosen so that the equations
28.4 mL: 30 mL: Traditional Scottish spirits measure Peg (India) 1 imp fl oz-28.4 mL: 30 mL: Also called a "small peg"; a "large peg" is a double measure of 2 imperial ounces (60 mL). Traditional spirits measure on the Indian subcontinent. 1 ⁄ 4 Gill (Irish) 1 + 1 ⁄ 4 imp fl oz: 35.5 mL: 35 mL: Traditional Irish spirits measure Pony (U.S ...
These ancient measurement systems spanned systems of counting, distances, volumes, time, weight as well as tools used to do so. While modern India uses the metric system International System of Units (Tamil Nadu state included), some of these older day measurement systems, especially those of counting, are still used today.
