How is
Tape Measured?
Its'
Pretty Confusing

 |
Tape manufacturers use both
the metric system and the standard measuring system when designating
tape sizes.
The thickness of the tape
is measured in "mils" which translates to "thousandths of an
inch". Good quality gaffers tape is at least 12 mils thick.
The width of a roll of tape
is measured in millimeters or "thousandths of a meter. Even
though a standard roll of duct tape is considered to be two inches
wide, it is actually only 48 millimeters wide.
The most common lengths of
tape are 60 yards for most cloth tapes and 36 yards for most vinyl tapes.
Why tape makers continue to
mix measurement standards may remain a mystery forever. |
