Here are some examples of converting the VOLT display into different units of 
measurement.    For  these  examples,  let  us  assume  a  fiber  length  of  1.25 
kilometers as shown by the display at right.

kilometers to meters

1.250 x 1000 meters = 1250 meters

kilometers to miles

1.250 x 0.6214 miles = 0.777 miles

kilometers to feet

1.250 x 3281 feet  = 4101.25 feet

Conversion Factors

The VOLT displays fiber length in kilometers.   At times it may be necessary to convert the fiber length to a 
different  unit  of  measurement.    The  table  below  provides  conversion  factors  for  various  units  of 
measurement.

To calculate the units you need, multiply the number on the VOLT display by the conversion factor listed in the 
table below:
