Switching between inches and millimeters on your Qfun SDK1-117 Vernier Digital Caliper is straightforward. First, power on the caliper by sliding the device. Then, look for the "unit" button on the digital display; it's often marked with "mm" and "in". Press this unit button to toggle between millimeters and inches. The display will change accordingly. Press the unit button once to display millimeters, and press it again to revert to inches. Repeat this process as needed for your measurements. For visual aids and more detailed information, please consult the Qfun SDK1-117 user manual.
