Accuracy has more to do with the measurement lines on the ruler than the material. In terms of making measurements , however, a steel ruler has several advantages to a plastic ruler of the same accuracy. For starters, steel rulers are often thinner than plastic rulers, positioning the measurement lines closer to the paper. As well as this, many steel rulers feature a backing made of a gripping material such as cork, which keeps the ruler firmly planted while drawing lines and making measurements. Lastly, the measurement lines on steel rulers are frequently embedded into the metal, whereas plastic rulers tend to have the lines painted on. After a while, these marks can be worn away, reducing the accuracy and readability of a plastic ruler.

What are the benefits of a stainless steel travel cup over a plastic one?
Stainless steel travel cups with wall insulation are better at keeping drinks hot than plastic travel cups. They also break less easily and are easier to clean. Plastic cups are much more likely than steel to become stained and unsightly over time. Taste may be a benefit of a stainless steel travel cup over a plastic one, depending on personal preference.
What metal are bottle caps made of?
Bottle caps are typically made of steel or aluminum. Steel caps are commonly used for glass bottles, while aluminum caps are more common on plastic bottles. Both materials are preferred for their durability and ability to preserve the freshness of the contents.
Why is iron more useful than steel?
Steel is more useful compared to Iron because it doesn't rust as easily and it is more durable than iron. Iron is more maleable than steel which makes steel more useful than iron.
Which is more accurate glassware?
It depends on the specific glassware being compared. Borosilicate glassware is generally more accurate and resistant to thermal stress than regular soda-lime glassware due to its higher thermal resistance and lower coefficient of expansion. However, in certain applications, such as disposable plastic labware, accuracy may be more dependent on the manufacturing process rather than the type of material used.
What is the difference between Aluminium alloy and steel?
If the steel contains by weight one or more of the following elements in the proportion shown, it is an alloy steel. 0.3 % or more of aluminium 0.0008 % or more of boron 0.3 % or more of cobalt 0.4 % or more of copper 0.4 % or more of lead 1.65 % or more of manganese 0.08 % or more of molybdenum 0.3% or more of nickel 0.06 % or more of niobium 0.6 % or more of silicon 0.05% or more of titanium 0.3 % or more of tungsten (wolfram) 0.05 % or more of zirconium 0.1 % or more of other elements (except sulphur, phosphorus, carbon and nitrogen), taken separately. Any steel not containing one or more of the above elements in the weight proportions shown, is a non-alloy steel.
Which is more accurate ruler or a vernier caliper?
A caliper is more accurate.
Which is more accurate an ordinary plastic ruler or a vernier caliper?
The vernier caliper is more accurate that a plastic ruler. That's because the caliper is designed to be used and effectively read to measure small distances. And it does this better than a "regular" ruler because it has a vernier scale built into it. It's like an "amplified ruler" attached to the device that has increased accuracy. A link is provided to the Wikipedia article on the vernier caliper and to the one on the vernier scale. Check out the pictures and skim the details. You should be able to pick it up with a bit of thought.
What is the different between steel conduit over plastic conduit?
Steel conduit weighs more, provides more protection, and costs more than plastic conduit. Plastic conduit weighs less, is easier to work with, and costs less than steel conduit.
What are the advantages of using plastic over steel wings on windmill is stell costlier or plastic?
Using plastic over steel wings on a windmill is a good idea because the steel will eventually rust. The steel is heavier and the motor on the windmill will have to work harder to turn steel, than plastic. The cost of the plastic is actually a little more than steel, though.
What is an angle ruler?
An angle ruler is a tool used to measuring angles like a protractor. An angle ruler is more accurate than a protractor.
Why does a piece of steel heat up more than an equal mass of plastic when both absorb the same energy?
Steel is more conductive than plastic is. The reason for this is that iron is more reactive than plastics are as they have valence electrons and plastic does not.

What weighs more a pencil or ruler?
Depends on the length AND material of both. The generic comparison between a 15cm wooden pencil, with a 30cm plastic ruler: most likely the ruler weighs more.
What metal would be more plastic or ductile a fine-grained steel or a course-grained steel?
G
Why is a metal ruler stronger than a plastic ruler by terms of the kinetic theory?
A metal ruler is stronger than a plastic ruler in terms of the kinetic theory because the metal atoms are arranged in a tightly packed, orderly structure which gives it greater strength and cohesion. The metal ruler's atomic structure allows it to better withstand external forces and deformation compared to the more loosely arranged atoms in a plastic ruler.
Which is more precise measurements a wooden ruler or plastic ruler?
Precision is the agreement among several trials in measurement therefor, a wooden ruler is more precise because you will be estimating the measured value over and over again
