Length Units and Conversion - Unit Calculator
The calculator converts between length units.
%cm 1.6m
The calculator will show 160.0 cm. %cm means the unit of result value is cm.
\[ 1.6 \mathrm{m} = 160.0 \mathrm{cm} \]
Note that 1.6m can't be input like 1.6 m. There is no space between number and unit.
The calculator regard % as the command of unit conversion. There is no space % and unit so % cm makes no sense. %cm is correct.
Another example:
Multiple arguments
Multiple values can be input and the calculator automatically sum them and convert. So if you input
%m 3km 740yd
the sum of 3km and 740yard is converted to m unit. The result is 3676.656 m.
Result:
3676.656 m
Metric prefix
10cm has cm unit and c is the metric prefix of m. m is a standard unit of length and prefix c (centi) means the scale means 10-2. In fact, 1cm = 10-2m.
There are many prefixes scaling from y (10-24) to Y (1024).
