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.
It's more precise.
The vernier caliper was invented in 1631 by Pierre Vernier, a French mathematician and inventor. It allows for more precise measurements than traditional measuring tools due to its vernier scale.
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 screw gauge has a smaller pitch than a Vernier caliper, which allows for more precise measurements. The screw gauge also provides a digital reading, which reduces human error in reading measurements. Additionally, the screw gauge has a finer scale that allows for more accurate readings compared to a Vernier caliper.
The least count of vernier caliper is 0.01mm while the least count of screw gauge is 0.001 mm. ... Difference between screw gauge and vernier caliper in tabular form. Micrometer Screw Gauge Vernier caliper It has a circular scale. It has a vernier scale. It rotates to measure the objects. It slides to measure the length.
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.
there is a big different between the vernier caliper and micro meter caliper,the vernier caliper they can use the outside and inside measurement while the micro meter caliper it's just only use outside measurement..
