Use the chart below to determine the volume per length of tubing, based on the inside dimension (ID). Note that VICI Jour 1/16" OD tubing typically has an ID tolerance of ±.001". This is a much tighter tolerance than normal commercial grades of tubing; however, it is enough to result in noticeable error if exact volumes are not measured.
