If you're talking about metric to imperial I think I can help! As an inch is 2.54cm and is usually referred to in thousandths, the metric system tends to be more precise as mm are usually used. As you can probably see though, you can get the same measurements from each but in a different format. EG. a thousandth of an inch is 0.00254mm but a thousandth of a mm is 0.001mm So really what I'm saying is.... choose your preference!
Depends on what you are measuring.
ans2. Accuracy is usually paramount. The True Value of a measurement is defined as 'the value towards which measurements tend, being made by competent experimenters and using different equipments'.
Accuracy is the amount by which your measurements approach the True Value.
And there are expressions for repeatability, reproducibility, and resolution.
A strain gauge (digital) balance will often be the most accurate piece of laboratory equipment.
Though not commonly realized, Mercury-in-glass thermometers are not very accurate, and they suffer from errors due to their recent history. As is true of much glass equipment. Volume is perhaps the least accurate of measurements.
So far I have referred to the Chem lab. But in the Electrical Lab, you will find the highest accuracies. And by association, Time measurements.
It would be impossible to have the MOST precise result, as you can always be closer. The smallest official Metric unit would be the Yoctometer for distance.
The prefix "Yocto-" means 10-24.
Which group of measurements is the most precise (each group of measurements is for a different object)?
A 2g,3g,4g
B 2.0g,3.0g,4.0g
C 2g,2.5g,3g
D 1g,3g,5g
Answer - In precision measuring, look for numbers that are closest to each other in the data set. Here, the most precise would be C 2g,2.5g,3g because they are closer to each other than the numbers in the other sets.
The precise number of choices listed with the question is zero.
A mechanical pencil.R7.
A micrometer would.
Millimeters
what unit of measure is thickness og a ballpen
Sheet metal thickness can be measured in mm. Sheet's thickness is very less.
The word accurate is a synonym for precise. So the most accurate (or precise) answer would be 57.213 because it is more accurate if the number is not rounded.
Yes, the markings on your 50 mL beaker would be accurate enough to use for precise meansurement of volumes. The markings on a 50 mL Erlenmeyer flask would also be accurate enough.
the accumulation of the daughter isotope and the loss of parent isotopes
Verniers give you a less accurate approximation of the thickness, whereas a micrometer can give a more accurate measurement, often by 100 orders more accurate.

Coins are measured in millimetres.
Millimetres, as in 1.5 mm. You could use a micrometer to measure thickness of a coin.
Is a desirable thing in science.
Sheet metal thickness can be measured in mm. Sheet's thickness is very less.
ordinal
Units aren't used to measure anything. After you complete the measurement, using equipment suited to the purpose, you use units to describe the result of your measurement, and to tell other people about it. I would measure the thickness of a hair using a micrometer, and express the result in millimeters.
Any measurement smaller than 35mm. That measurement would depend on the thickness of the material making the tube
