millimeter
What determines how precise a measurement is
It is precise if it is repeatable.
Unit of measurement 1000 times less than the millimeter is the micrometer. Unit of measurement 1,000,000 times less than the millimeter is the nanometer.
Millimeter is a size measurement; carat is a weight measurement. Take the stone to a local jeweler and ask for its weight.
the nearest millimeter
The measurement 25.81 is precise to the nearest hundredth.
By using a precise instrument. One that is calibrated by a recognised body.
millimeter
the nearest .01 mL
This should not be taken as a precise measurement of 1 mm, but this hypen: - is approximately a millimeter in length. It's the closest I can do on the keyboard.
If you are using a ruler, measure one digit more than the ruler reports. For instance, if you have a ruler that reports to the nearest millimeter, you will write your answer to the nearest tenth of a millimeter. (Estimate the last digit).
What determines how precise a measurement is
5011m is more precise. This is equal to 5.011km. Is is therefore measuring to the nearest one thousandth of a km, whereas 5km is (unless stated or implied otherwise) written to the nearest km.
How can it be rounded to the nearest millimetre, when you have NOT specified the units for '28.26'? Is it metre(m) , Centimetres(cm) or millimetres (mm)?
Millimeter is the smallest measurement.
It is precise if it is repeatable.
