Mainly because the meter stick is thicker and if your eye isn't exactly over the mark you are measuring there will be an error due to parallax. The thinner the measuring device the better result you achieve.
There's no such measurements as mini meter and centermeter.
So that the result that you find on the watt meter after resetting it will be accurate
Meter Volume Weight ====================== Mass Length Time Electric charge All other measurements are combinations of these.
Concrete is sold in cubic (volume) measurements not square (area) measurements.
The SI unit of length is the meter. Shorter lengths are commonly expressed in centimeters, or millimeters. The chosen unit doesn't affect accuracy; if the wire has (for example) a length of 245 millimeters, then each of these measurements: 245 millimeters, 24.5 centimeters, 2.45 decimeters or 0.245 meters are just as accurate as the others.The SI unit of length is the meter.

A vernier caliper.
Used correctly, they can be equally accurate. Each may be better in a particular circumstance. The error in a series of measurements increases the more measurements need to be taken. So, for instance, in order to measure a 100 meter tall building with a meter stick 100 measurements must be taken. With a 50 meter measure only two measurements are taken. If the margin of error in all measurements are equal, the error using the meter stick will be about 7 times more than the error using the measure. (Why 50 times as many measurements gives only 7 times the error is the subject of another answer.) On the other hand, when measuring the overall length of an irregular object it is useful to have a rigid meterstick in order to avoid the tendency to follow the object's contour. It is best, as always, to use the right tool for the job.
The caliper and micrometer use a dial or digital readout to measure the distance between the tips. The tolerances of these tools can be under .001 inch, making them extremely accurate.
Advantage : Using a meter stick helps us to make measurements straight and to get the accurate measurements. It can be used for measurement of greater objects. Disadvantage : Meter stick cannot properly read measurements of small distances and objects having dimension of 0.053 cm

Accuracy
The meter and gram are measurements in the SI, or the metric systems. These measurements are comparable to a foot and an ounce.
A meter is approximately:The height of a child.The length of a large step.The width of a table.You may want to do some measurements to see which is close enough for your purposes. You can measure some other things, too.
There's no such measurements as mini meter and centermeter.
There is no danger in using a laser distance meter, however when taking measurements, one must take extra precaution that there is no interference of the laser or this could result in a false measurement.
meter sticks give precise measurements and in order to get the full precise answer you should start where the numbers start at on the meter stick.
In the SAE, Imperial and US Customary systems, we normally use inches, feet, yards and miles. In the metric system, used in all scientific measurements, we use various degrees of the meter, including the millimeter, centimeter and meter for larger measurements and divisions such as the nanometer (one billionth of a meter) for microscopic measurements. For atomic and molecular sized measurements, we use angstrom units (one ten billionth of a meter).
