1. In physics, there are seven fundamental physical quantities (which are measured in base units, or fundamental physical units): length, mass, time, electric current, temperature, amount of a substance, and luminous intensity.
2. This page explains the two most common systems of measurement: the metric system, used widely in Europe and most of the rest of the world, and the Imperial or British system, a form of which is now chiefly used in the USA.
3. At this time, only three countries—Burma, Liberia, and the US—have not adopted the International System of Units (SI, or metric system) as their official system of weights and measures." We should point out that even these three countries do use elements of the metric system
4. Imperial units
units of measurement of the British Imperial System, the traditional system of weights and measures used officially in Great Britain from 1824 until the adoption of the metric system beginning in 1965. The United States Customary System of weights and measures is derived from the British Imperial System.
5. Decimal fractions were first developed and used by the Chinese in the end of 4th century BCE, and then spread to the Middle East and from there to Europe. The written Chinese decimal fractions were non-positional.
6. In the metric system, the basic unit of length is the meter. A meter is slightly larger than a yardstick, or just over three feet. The basic metric unit of mass is the gram.
9. Student Answers. hazie123 | Student. The unit of mass is the kilogram (kg), but commonly, when we measure something in kilograms, we are measuring the force of gravity on that mass, which should be measured in newtons (N), (a measure of force).
1. Physics measures such physical quantities as time, length, mass, density, velocity, area, volume, temperature and energy. Different units of length and mass exist. Nearly all of them are interrelated.
2. Three systems (the British system of unity, the metric system of units and the International system of units (SI))
3. With а few exceptions, all the nations of the world use the metric system.
4. The British foot- pound-second system. It was very complicated and caused serious difficulties in the international trade.
5. Аt the end of the 18th century.
6. Тhe standard of length should bе one ten-millionth part of the distance from the Equator to the North Pole. The two French scientists charged with the task took this distance on а line running through Paris and divided it into 10 000 000 equal parts.
7. Yes. Metre was also used to measure area and volume.
8. 'Millimetre' is Latin for 'а thousandth part of а metre' and 'kilometre' is Greek for 'а thousand metres'.
9. The mass of а cubic centimetre of water at the temperature of 4 degrees.
10. With some differences in details, system elements are the same all over the world.
