Length Calculator

There is no way to accurately calculate the length of an idea or story. It's simply a notional value. For example, this sentence has five words, so it would be 5 words in length (not counting the space between the quotation marks).


In England, the foot measure also changed through the ages - it started from Roman standards, then Belgic Celts foot of 13.2 inches or Welsh foot came and went. The feet definition varied from region to region, city to city, later even the kings changed the measure according to their desire - e.g., Henry I was said to have ordered a new standard based upon his arm. Then Edward II of England introduced some kind of standardization by introducing the statute foot which was 10⁄11 of the old foot. The final agreement on the foot length came much later, in 1959, when the international yard and pound agreement was accepted. Since then, yard in the United States and countries in the British Commonwealth is equal to exactly 0.9144 meters. As yard was defined, the foot could be calculated as well. Thus, it's equal to: 1799 - 1889, brass, platinum, and the alloy of platinum with 10% iridium meter bars were constructed, still as a basis having Earth's meridian length. The 1st General Conference on Weights and Measures in 1889 defined the meter as the distance between two lines on a standard bar of the latter type of alloy. This International Prototype Meter is still kept in the International Bureau of Weights and Measures in Sèvres, near Paris. That meter definition was in force till 1960 and the 11th General Conference on Weights and Measures. In the past, many systems of measurement were defined on a local level, and could be based on factors as arbitrary as the length of a king's thumb. While this may work on a local level, when considering trade, as well as science, having systems of units based on units that others may not be able to relate to or understand makes interaction difficult. As such, the development of more universal and consistent systems developed over time. Today, some of the systems of units in use include the metric system, the imperial system, and the United States customary units.

The International System of Units (SI) is the standard metric system that is currently used, and consists of seven SI base units of length, mass, time, temperature, electric current, luminous intensity, and amount of substance. Although SI is used almost universally in science (including in the US), some countries such as the United States still use their own system of units. This is partly due to the substantial financial and cultural costs involved in changing a measurement system compared to the potential benefit of using a standardized system. Since US customary units (USC) are so entrenched in the United States, and SI is already used in most applications where standardization is important, everyday use of USC is still prevalent in the United States, and is unlikely to change. As such, many unit converters including this Conversion Calculator exist, and will continue to do so to ensure that people globally are able to communicate different measurements effectively. Different systems of measurement also developed over time in Asian countries. For example, in ancient India, a measure of weight called the "Satamana" was used, and was equal to the weight of 100 gunja berries. In China, the first emperor Shi Huang Di created a system of weights and measures in the third century BCE (Before the Common Era). The measurement of weight was based on the shi, which was equivalent to approximately 132 pounds. The Chi and Zhang were units of length equivalent to approximately 25 centimeters (9.8 inches) and 3 meters (9.8 feet) respectively. The Chinese also developed a means to ensure accuracy through the use of a special size of bowl used for measurements that also made a specific sound when struck – if the sound was off pitch, the measurement was not accurate.

Calculates the rolled length of a roll of material when the outside diameter of the material, thickness of the material, and the diameter of the hole in the center or the tube on which the material is wound are given. Variations due to stretching or softness of the material are to be ignored. An example of rolled material would be a rolled carpet or a rolled sheet of paper from the paper mill. The length units that can be used are yard, feet, inch, meter, centimeter, millimeter, mil, and micron. A mil is equal to one thousandth of an inch. A micron is equal to one thousandth of a millimeter. The initial units used in the table can be changed to any of the choices given.

Exposure C: Open terrain with scattered obstructions, including surface undulations or other irregularities, having heights generally less than 30 feet extending more than 1,500 feet from the building site in any quadrant. This exposure shall also apply to any building located within Exposure B type terrain where the building is directly adjacent to open areas of Exposure C type terrain in any quadrant for a distance of more than 600 feet. This category includes flat, open country and grasslands. Bracing in Exposure C buildings will increase 20-40% over Exposure B amounts.Exposure D: Flat, unobstructed areas exposed to wind flowing over open water (excluding shorelines in hurricane-prone regions) for a distance of at least 1 mile. Shorelines in Exposure D include inland waterways, the Great Lakes and coastal areas of California, Oregon, Washington and Alaska. This exposure shall apply only to those buildings and other structures exposed to the wind coming from over the water. Exposure D extends inland from the shoreline a distance of 1,500 feet or 10 times the height of the building or structure, whichever is greater. Buildings in Exposure D will have a 50-70% increase in bracing. (Source: www2.strongtie.com)
