How to use the meter ruler? Is it used without digital measurement in front? 0 1 2 3

First, take the "0" of the meter scale as the starting point and align the scale; (that is to say, if there is no number in front, you don't need it. Generally speaking, those are for the convenience of measurement, so you can pinch them. Just like a steel tape measure, there should be a small piece to pinch without affecting the measurement data. )

The second is to straighten when using the soft ruler.

Conversion unit:

1. 1 m = 3 feet, so 1 ft = 1/3 meters = 0.3333 meters.

2. 1 m = 100 cm, 1 ft = 10 inch.

So 1 inch =10/3cm = 3.3333cm.

I hope I can help you!
