The zero error (if positive) is the distance from the edge of the ruler to the point where the actual measurements begin or (if negative) is the length that has been lost - through abrasion - before the point where the measurements should start.
Many meter rules are marked in centimetres. The reading uncertainty for such rules is 0.5 cm (= 5 mm).

A metre rule.
Normally from 0 to 1 metre.
The zero error for a meter rule is when the ruler's zero marking is not aligned with the starting point of the measurement scale. The reading uncertainty for a meter rule can typically be within ±0.5 mm due to parallax errors or imperfections in the ruler.

Balancing the meter rule on the wedge edge-wise ensures that the weight of the meter rule is evenly distributed on both sides, leading to a stable and accurate reading. Placing it edgewise helps minimize the effect of friction and other external forces that may affect the balance of the rule.
What's the function of meter rule
If the uncertainty in the position of an electron is zero (meaning it is known precisely), then according to the Heisenberg Uncertainty Principle, the uncertainty in its momentum would be infinite. This is because the product of the uncertainties in position and momentum must be greater than or equal to a certain constant value determined by Planck's constant.

If the calibration starts from the edge of the stick then it is a meter rule Basically "0" starting from the edge And if it is a meter ruler ,there is like half inch of empty space before 0
A rule or steel tape is more accurate in taking measurements because they have finer increments or markings compared to a meter stick. This allows for more precise readings, especially when measuring small or detailed objects. Additionally, their durability and flexibility reduce the risk of bending or warping during measurements, which can affect accuracy.
Measuring anything up to a metre (meter in USA); drawing straight lines. Rule is the "proper" word for what most of us call a ruler.
