That refers to the marks - for example, a ruler may be marked with centimeters and millimeters. The centimeter marks are somewhat longer (to distinguish them easily); the millimeter marks are usually the smallest division - the smallest unit that is marked on the scale.
The size of the smallest scale division on an instrument, often referred to as the least count, varies depending on the specific instrument being used. For example, a standard ruler may have divisions as small as 1 millimeter, while a micrometer can measure to the nearest 0.01 millimeter. The precision of the instrument determines its smallest scale division, which is crucial for accurate measurements.
The experimental error when using a ruler can arise from several factors, including parallax error (misreading the measurement due to viewing angle), the precision of the ruler's markings, and human error in aligning the object with the measurement scale. Additionally, environmental factors such as temperature can cause expansion or contraction of the ruler material, affecting accuracy. Generally, the smallest division on the ruler indicates its precision, and the overall error can be estimated as half of this smallest division.

To find the precision on a ruler, look at the smallest division or marking on the ruler, as this indicates the precision of measurements that can be made using the ruler. For example, if the ruler is marked in millimeters and the smallest division is a millimeter, the precision is 1 millimeter.
what are the smallest units on a metric ruler?
The smallest main scale division in a vernier scale with 50 divisions is 1/50th of the main scale division. This is because each division on the vernier scale corresponds to 1/50th of a main scale division, allowing for more precise measurements to be made.
The least count of a metric rule is determined by the smallest division on the scale of the ruler. To calculate the least count, divide the smallest marked division on the ruler by the total number of subdivisions between two main unit markings. For example, if a ruler has millimeter divisions with half-millimeter markings between each millimeter, the least count would be 0.5 mm.
Epoch
The smallest division on the main scale of a micrometer gauge typically corresponds to 0.5 mm or 0.025 inches. This is the precision at which the main scale can be read.

The smallest division on the main scale of a vernier caliper typically corresponds to 1 millimeter. The vernier scale allows for more precise measurements by measuring to the nearest 0.1 millimeter.
The smallest division on the main scale of the vernier calipers is typically 1 millimeter, while the smallest division on the screw gauge is typically 0.01 millimeters, also known as 0.01 mm.
