Unusual units of measurement on Earth
A person has something to consider, so people for many years came up with a variety of units. In this article we will talk about the yards, miles or feet, but the more stupid units, the existence of which many of us have not even heard of.
To be more precise, not hand and hand. This amount of English use to measure horses. 1 hand (hand) is about 4 inches. In the usual measurement system it will be 10.16 centimeters.
Banana equivalent dose
All grown in the garden or in the garden products contain radioactive isotopes, though in small amounts, this also applies to bananas. For example, in one African fruit weight 150 grams contains about 0.42 g of potassium, and it says that the banana is a radioisotope, the activity of which 520 picokuri. This number was called the «banana equivalent». If you will daily eat one banana, then for a year you expose yourself to radiation in the 3.6 millibar. It really is a small amount, so no need to worry there.
The land of saints and scholars, the so-called ancient Ireland, for the farmers was important, not the area of existing fields, and how they are useful. Therefore, it was convenient to measure their bows in Cow’s Grass. What does that mean? They evaluated how the meadow to feed the cow. In the United States used another method of measuring Mother Cow Index. The field area was assessed by the ability to feed the cow tive on a particular plot of land.
In Britain, one of the ancient units of measure is the Barleycorn or 1/3 of an inch. Currently, the United Kingdom of great Britain use it to measure Shoe sizes.
Using this unit in Australia to measure the water. Sidhar equal to the volume of water in Sydney Harbor (Sydney Bay).
We all remember the cartoon about Mickey mouse, so here are some geeks to determine the sensitivity of the computer mouse began to use such a meaningless concept as «per inch Mickey». This measurement unit defines the smallest movement of the mouse on the surface, usually in the range 1/200 to 1/300 inch.
Many fear this word. But this isn’t about the morgue, and about the German word morgen, which means «morning». This value is used in the middle ages in Western Europe for measuring land area. 1 morgue equal to 0,56 ha. However this value is different not only in other countries, but in the fields.
The fact that the morgue is equal to the area of land that can be prepared for planting by one man in one working day. And here «morning»? It turns out that the field work begins with sunrise and ends at noon.
One of the famous physicists in Britain was Paul Dirac. It was such a silent man that his colleagues have even invented comic value measurements the «Dirac». One word per minute – this is the unit «Dirac».
As it turned out, not every size is able to fit in. It happened with sirimadam invented by the astronomer Carl Charlier. Sirometer equaled 1 million astronomical units. This value was trying to use it, but to no avail. Currently the astronomical distances measured in parsecs.
This value is used by sociologists to determine the risk to human life. It is equal to 1×10-6 of the probability of death. Every day, each of us is exposed to death, simply for the reason that all will die sooner or later. This kind of «natural» dose of micromart. In each country, the value of this probability can vary. For example, in England the figure is 41.6 per micromart, and in less prosperous countries, it increased in several times.
Every human action can be measured in micromart. Smoking 1.4 cigarettes living for two months with the best man in the same room, drinking 0.5 liters of wine, you increase the probability of death at 1 micromart.
