A caliper is more accurate.
A vernier caliper.
Vernier calipers is more convenient to use compared to the external and internal calipers because vernier caliper by its own could be used as external and internal calipers. When using Vernier caliper you can identify the measurement withtout using ruler, meter stick etc. but the internal and external calipers rely on measuring tools to know the exact measurement... (*Ivan Richmond Jumawan*).
It depends on what you are trying to measure. If you are measuring the length of a car, for example, any reading obtained using vernier callipers is likely to be totally useless. The key is to select a tool that is appropriate to the task.
A vernier caliper would be a good way, unless you need a more accurate measurement, in which case I might use a micrometer caliper.
A caliper is more accurate.
It depends how accurately you can read the scale. A ruler would only be accurate to 1 mm. If the caliper has a vernier scale it should be ten times better
it directly obtain a more precise measurement
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.
A digital caliper displays measurements on a digital screen, while a vernier caliper requires reading a scale. Digital calipers are generally more precise and easier to read, making them better for precise measurements in my opinion.
A vernier caliper has an additional scale that allows for more precise measurements compared to a regular caliper. This increased precision is due to the smaller increments on the vernier scale, which can help in obtaining more accurate measurements.
It is the measuring instrument it is invented by verniers its error is very small
It's more precise.
A vernier caliper uses a sliding scale with a main scale and a vernier scale to measure length, while a digital caliper uses electronic sensors to provide a digital readout. Digital calipers are generally more accurate for precise measurements due to their digital display and ability to provide measurements in decimal form.
A vernier caliper.
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.
A caliper is a measuring tool with two jaws for measuring the distance between two points, while a vernier caliper has an additional scale for more precise measurements. Vernier calipers are generally more accurate and precise than regular calipers due to the additional scale, allowing for measurements to be taken to a higher degree of precision.
