In geometric measurements and the International System of Quantities, the definition of length varies based on the context. The unit of length that we use in daily life is synonymous with distance, this is what applied in the physical sciences and engineering. Based in the requirements, there are various units to measure length.
 
It is noted in historical texts that the first units of length, in the absence of measuring tools, was probably based on the ingenious use of human body, such as length of arm and distance covered in a stride. It is no surprise that foot is still used as the unit of measurement.
 
Now, the International System of Units (SI) defines unit of length as the metre in terms of speed of light. Other units such as centimetre and kilometer, came into existence to measure smaller distance precisely, and are derived from metre only.
 
Since in U.S. and English system of units use different terms, such as inch, foot, yard, and mile, length unit conversion become essential. Use our conversion table to get precise measurement up to 6 decimal values.
 
All this can be done easily with the help of this online conversions tool.

Length Unit Definition:
Length - according to the geometric definition, length is a quantity that describes the longest dimension of an object. In Euclidean space, it?s how far 2 specific points are from each other.
The standard SI unit of length is the meter.
