Measure by liters and cubic meters volume. Only the meter is unit of the international SI system, and the liter does not. Let's consider how these two units of volume which names to us meet nearly daily are connected among themselves.
It is required to you
- - calculator,
- - computer with the Windows 7 operating system or connection to the Internet.
Instruction
1. Increase the interesting number of liters by 0.001. The received work will also express the same volume, but already - as one liter is equal in cubic meters to 0.001 CBM.
2. Except this way, there is an opportunity to transfer units of measure (in particular from liters to meters cubed) by means of the converters working online or using the standard calculator of the Windows XP, 7 or Vista operating system.
3. Gather in a window of the searcher (Google, Yandex, Nigma, etc.). The necessary expression, for example "" in liters10 cubes"". In the searcher the converting function is already built-in.
4. Open the calc.exe file in the computer. Execute necessary transfer of liters to cubic meters - the translation panel of units of measure is displayed to the right of the main panel of the calculator.
5. It is interesting that the ratio of liter and cubic meter was "finally legalized" only in 1964. Before, since 1901, the liter was defined how one kilogram of water without impurity with a pressure of 760 millimeters of mercury and temperature of 3.98 degrees Celsius, the corresponding maximum density of H2O. That is the difference from the modern liter equal to one cubic decimeter, from liter of a sample of 1901 was 0.000028 cubic decimeters.
6. In the 18th century the meter had several definitions. On one of them, meter was called pendulum length with the swing half-cycle 1 second suspended in a certain place (specifically, at the width of 45 degrees). The difference of this meter and modern made 6 mm. Other definition (the same as before league and nautical mile) tied meter to the Parisian meridian: for meter the distance equal its one forty-million part was accepted. This meter is almost equal modern (the error is insignificant it is small). Nowadays for meter the work of a certain number and the wavelength radiated by krypton isotope is accepted.
