CONVERSION CALCULATORS BETWEEN METRIC AND U.S. UNITS FOR LENGTH, MASS, VOLUME AND AREA

<------------------------------------------------------------------------------------------------------------------------------------------------------------------->

The metric system is a system of units based on meter, kilogram and second. Its main advantage is it's decimal: all fundamental units are divided into fractional units, and enlarged into multiple units, based on power-of-10 prefix multipliers. Currently it is the basic measurement system in practically entire world, except for the U.S.

The online calculators below let you quickly convert values from metric system into traditional ones and vice versa. You can find for example the values of such commonly used in household measures as teaspoon, drop, cup, etc. To use these calculators just enter the value to convert from into the box on the left. Select the unit to convert "From" in the left pull-down list. Then select the unit to convert "To" in the right list. The result should appear below.
Besides common SI, metric and US/imperial quantities, this tool contains some relevant physical constants and reference data, such as diameter of Earth, sun to Earth distance, etc.
