## When you are looking at a drawing How do you know if you are looking at us customary or SI measurements?

1. When you look at a drawing, how do you know if you are looking at U S Customary or SI measurements? Why is it important for an engineer to know this piece of information? Answer: You can tell by the labels by the measurement.

## How can you tell the difference between US Customary and SI measurements?

SI unit of length is metre,For measuring length, the U.S. customary system uses the inch, foot, yard, and mile. For area the U.S. customary system uses the unit acre. . The U.S. customary system uses the cubic inch,cubic foot and cubic yard for measuring volume.

What is the difference between precision and accuracy?

Accuracy and precision are alike only in the fact that they both refer to the quality of measurement, but they are very different indicators of measurement. Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value.

Why would you have to know how do you convert measurements when looking at working drawing?

1. Why would you have to know how to convert measurements when looking at a technical drawing? Answer: To have the ability to remodel the design.

### What is SI equal to?

The International System of Units (SI) equivalent is 0.0025 ng/J. The SI equivalent for 2 in is determined by multiplying 2 in × 25.4 mm = 50.8 mm, then rounding to 51 mm. The SI equivalent for 2 in is determined by multiplying 2 in x 25.4 mm = 50.8 mm, then rounding to 51 mm.

### What measurements do us use?

The U.S. is one of the few countries globally which still uses the Imperial system of measurement, where things are measured in feet, inches, pounds, ounces, etc.

What does it mean to be precise but not accurate?

Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy. If all of the darts land very close together, but far from the bulls-eye, there is precision, but not accuracy (SF Fig.

Why would you have to know how do you convert measurements?

Help to show another person the exact amount you have. Assist in solving a mathematical problem, especially in chemistry, where you can follow the units to get to the answer. Show which measurement system the person is using (i.e. metric or standard)
