A caliper is more accurate.
A vernier caliper.
A vernier caliper would be a good way, unless you need a more accurate measurement, in which case I might use a micrometer 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*).
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.
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.
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.

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
The micrometer caliper is generally more accurate in measuring the density of an object compared to the vernier caliper. This is because the micrometer caliper has a higher precision and can measure with greater accuracy, typically up to 0.01mm.
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.
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 uses a sliding scale with a vernier scale for precise measurements, while a dial caliper has a dial indicator for readings. The vernier caliper is more accurate for measuring small distances, while the dial caliper is easier to read and use for quick measurements. The choice between the two depends on the level of precision needed for the measurement task.
The vernier caliper is used to measure linear dimensions, such as length, width, and thickness, with high precision. It can measure the distance between two opposite sides of an object by using a sliding scale and a vernier scale for more accurate readings.
The metric system is generally considered more accurate than the British system when using a vernier caliper, as it offers finer measurement increments. The metric system typically provides measurements in millimeters, which allows for more precise readings compared to the British system's inches and fractions of an inch.
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.
A dial caliper has a digital display for reading measurements, while a vernier caliper requires manual interpretation of scale markings. The dial caliper is generally easier to read and provides more precise measurements, making it more accurate for precision work. However, the vernier caliper allows for finer measurements due to its smaller scale divisions. Ultimately, the choice between the two depends on the level of precision required for the specific measurement task.
