The Old English word “acre” means field and it was generally considered the area that could be ploughed in a day using a yoke or oxen. Imperial / American measurements: These area measurements are mostly square versions of their linear conterparts except for the acre which is an area of length 1 furlong and a width of 1 chain. Metric area measurements are based on the meter, with the main unit being a Hectare, 10000m2.There are exactly 640 acres in a square mile. The Nautical mile is the distance across 1′ (1/60 of a degree) around the earths surface. A yard can be defined as the length of a pendulum that causes its arc to swing in exactly 1 second. ![]() Imperial / American measurements These measurements have a less logical progression. All other length and distance measurements in the metric system derive from the meter (eg. This calculator applies when attempting to express a pressure measurement in a. Quick, free, online unit converter that converts common units of measurement, along with 77 other converters covering an assortment of units. This puts the boiling and freezing points of water exactly 180 degrees apart.Ī meter has been officially defined to be the distance traveled by light in a vacuum in 1/299,792,458 second. This calculator will convert pressure values to ten different standard. For example, a liter of water weighs one kilogram.Ĭelsius: Zero on the Celsius scale (0 Â☌) is now defined as the freezing point equivalent to 32° F, At 100☌ the Celsius scale is defined as the boiling point and equivalent to 212° F.įahrenheit: Is a thermodynamic temperature scale, where the freezing point of water is 32 degrees Fahrenheit (☏) and the boiling point 212☏ (at standard atmospheric pressure). Metric weight units are based around the weight of respective metric volumes of water. It reports the standard base units of meter. ![]() Also, explore many other unit converters or learn more about pressure unit conversions. This calculator contains a wide range of units. We are not sure of the origins of a Barrel, Gallon or Pint. This calculator converts a single unit or a mathematical expression with units to the base metric (SI) units. Free online pressure converter - converts between 53 units of pressure, including pascal Pa, kilopascal kPa, bar, psi psi, etc. You can use this calculator to convert values to different units of measure, for example from feet to meters. Note that a US gallon is different from a UK gallon. ![]() Metric volume measurements are based around the liter of which there are 1000 in a cubic meter (ie.
