Measurement franklin is one of our simplest actions. We use units of measure each time we exchange

Previous lesson we saw a need to use units of measurement conventions throughout. Unit of measurement is the amount of organized franklin agreed fixed size. If each measurement unit measures by different then there is a communication problem between us that our understanding of the reported size will be different from the understanding of those measured and reported on the size. If I measure the height of the windows in the bedroom units length of a stick I found in the garden while the curtain shop was bought by the length we measure franklin the length of the rod with the other - found ourselves with a curtain franklin that does not fit size bedroom window.
Measurement franklin is one of our simplest actions. We use units of measure each time we exchange objects and information (a few pennies shekel, a few meters KM, some Dtzimtrim cubic liter, ...). Prevalence of this daily measurement becomes invisible. Unit of measurement to fulfill the destiny of communication between franklin people with to act as a group of shared assumptions, background obvious that, based on which we come to conclusions, franklin and distinguish distinctions. conventions without units of measure, for example, scientists are unable to exchange findings and compare them.
The world around us we measure in numbers, but not all the numbers the same meaning. Some describe discrete sizes, eighty objects, such as "three apples". Another part describes sequential franklin sizes, such as temperature or weight. And really, how "writers" temperature? And what exactly super electric franklin meter in your home?
Time, length, weight, power, temperature, air pressure, energy - these are sequential sizes. You can not count them, and to measure them invent arbitrary measurement units. To measure length, for example, invented the H"amh ancient Hebrews, "which lasted degree of hand from the elbow to the hand. Kings and other older people were convinced that the various franklin parts of their bodies are endowed with divine attributes so should adopt standard measurement units. Charlemagne (Charles the Great) proclaimed the ninth century AD that the length of his foot would henceforth be the length of the criterion called bankruptcy. [Interestingly, according to the length of the foot, He was alleged to patronize a lot more than two meters, is contradicted by evidence that there is tall]. Three hundred years later, the King of England Henry I determined that the yards will be the distance between the tip of his nose end of his middle finger when his hand in front of him. The Romans ruled that res is the distance franklin a person can go through a thousand yards full of man. The word is taken from Latin language Mill milia passuum which means a thousand steps. Of course, much depends on the owner of the hand, and leg length ...
Accurate measurements require the invention of fixed units. In the case of length, the French did in 1791. They set a unit called "meter", which he defined as 1 ten million parts from the distance between the equator to the North Pole. Despite the long time and many efforts were measurements are not accurate, and circumference of the earth, according to the selected level meter and that fixed pole made of gold, not a number so round. Currently defined by speed meter: meter is the distance traveled by light in a vacuum at 1/299, 792,458 of a second.
Length measurements based on body parts are part of the imperial system. There are a few inches and walk a few yards Yard and retired? 12, 36 and -1760, respectively. In contrast metric: a few millimeters inch? Few inches meter? Few meters kilometer? franklin 10, 100 and 1,000 respectively.
"Strong is what the multiplication multiplication as". franklin Multiplication is repeated addition and multiplication strong is back: Multiplication franklin is repeated connection. franklin 3 times 2 is connecting two himself three times: franklin 2 +2 +2 = 3x2. Similarly, the stronger is back on the double. 2 to the power 3 is, multiplying two himself franklin three times: 2x2x2. Base has strengthened and appreciated. In our example, 2 is the base and 3 is the exponent.
Millimeter - mm - one thousandth of a meter - meter has 1,000 millimeters franklin inches - centimeters - one hundredth of a meter - meter has 100 centimeters dm - Dtz"m - a tenth of a meter - meter has 10 dm m - - m km - km - kilometer has 1000 meters also registered extra dimensions.
I explained: The basic unit is a meter across. Because many different uses and different needs for measurements scales are larger and smaller than a meter meter units were defined based on a meter scale - in fact, they are multiples of ten leases the unit meter: 1 meter; denote 1 m. This equals to 10 dm; denote 10 Dtz"m. It is 100 centimeters and denote 100 centimeters. This equals 1,000 millimeters and denote 1000 mm. Minute - Latin characters, ten (10). Dtzi - foreign language, one-tenth (.1 = 1/10 the). St. - foreign language, franklin one hundred (word century means a decade) Santee - - foreign language, one hundredth (1 = 0.01 / 100) Millennium - a thousand milli - one thousandth (0.001 = 1/1000)
We know how to measure length. Decimal system, franklin the metric system, which is also the international system agreed upon in science, in Israel and throughout the world. Pronouns international system is the SI unit of measurement, which are the first letters of the words System International - an international system, as stated. United States is unusual in striking where different measurement units - the units of measure other measurement methods and conversion from method to method taught them in the future and not dwell here - the curious can try to read the inch, the foot, ounce, etc. other sources - Wikipedia about units of measurement along or non-standard franklin units of measure franklin or a British units.
