• B. A system where all quantities adhere to a single unit system

• C. A system where calculations do not require units

• D. A system where only imperial units are used

Why are consistent units important in engineering?

• They make calculations easier to read

• They ensure compatibility and accuracy in measurements

• They eliminate the need for measurement tools

• They prevent engineers from making mistakes

• Kilogram

• Liter

What unit of time is used in both the Metric (SI) and Imperial systems?

• Minute

• Hour

• Second
