A system (100) for measuring and cutting includes a portable measuring unit (110) and a cutting unit (140). The measuring unit (110) includes a transmitter (112) and a measuring processor (114) in communication with the transmitter (112). The measuring unit (110) includes a first retractable tape measure (116) having a first variable resistance wire (117) and a sensor (118), the measuring processor (114) having programming for determining first distance data and for transmitting that data. The cutting unit (140) includes a saw (141) and a receiver (142) for receiving the first distance data transmitted from the measuring unit (110). The cutting unit (140) includes a second tape measure (146) with a second variable resistance wire (147), sensor (148), and processor (144) for determining a second distance. When the second distance measurement is equal to the first distance measurement, an indicator (150) is actuated so the user knows to actuate the saw (141) to cut the workpiece. The system (100), therefore, eliminates inaccurate measurements and the need to remember or record measurements.
