Because important decisions are often made on the basis of measurements.
Would you like your doctor to diagnose your illness on the basis of a very rough measure of you pulse / blood pressure / etc. Would you like your builder to build a house on approximate vertical angles? Or your car to be designed on rough calculations?

What is the difference between an accurate and a precise measurement?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
Why is it important to use units of measurement that are the same for everyone?
when one scientist tells another scientist that something is certain length, that measurement should mean the some thing to both of them.
Is it true theme statement should be precise?
yes
What is a precise weight measurement?
Precise measurement of weight refers to repeated measurements taken for the weight of an object, in which all the results are very close to one another. They could all be wrong by the same value.For example, suppose you have a pair of kitchen scales which show 100 grams when there is nothing on them. Suppose you weigh a single bag of flour several times. The results may be 601g, 600g, 601g, 602g, 599g. The results are all within 1 gram of 600 g indicating a high degree of precision. But a totally useless result since the result is not accurate: the true weight is 500 grams, and the zero error has displaced each measurement.Actually, the weights should be given in Newtons (or millinewtons), not grams, which is a unit for measuring mass, but for the sake of simplicity I have indulged myself.
How many estimated digits are recorded as part of a measurement?
Your measurement should include one estimated digit.
What is the difference between an accurate and a precise measurement?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?
The final answer.is only as accurate as the least accurate component in the calculation, so use the significant figures of the measurement with the fewest.
What should be used to make a precise measurment of liquid volume?
A graduated cylinder or a volumetric flask should be used to make a precise measurement of liquid volume. These tools have calibrated markings on the side that allow for accurate measurements to be made. It is important to ensure that the liquid level is read at eye level to minimize any parallax error.
Should be used to make a precise measurement of liquid volume?
gradulated cylinder
How precise a measurement should be recorded when using the graduated cylinder?
the nearest .01 mL
What h of the following should be used to make a precise measurement of liquid volume?
Graduated cylinder
What are the two requirements of measurements?
( 1 ) Measurement should be accurate. ( 2 ) Measurement must have the correct units specified.
Why should quantities of colour and developer be mixed accurately?
Accurate mixing of hair color and developer are very important in order to have even color coverage and precise, true color results.
What was the need for creating a standard unit for measurement?
We need standard unit for measurement to make our judgement more reliable and accurate. For proper dealing, measurement should be same for everybody. Hope this helped :>
Do you have a picture of 1 mm?
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.
What is important for observations to be accurate and carefully recorded?
Observation should be accurate so that in future it can be use correctly.
An experiment was set up to measure the distance a snail would travel in 5 minutes Which of these rulers should be used to give the most precise measurement?
the ansewr is h
