Activity 3.2 Unit ConversionIntroductionEngineers of all disciplines are constantly required to work with measurements of a variety of quantities – length, area, volume, mass, force, time, temperature, electric current, etc. It is often necessary to be able to express those measurements in different units. For example, when designing a water distribution piping system, it is important to know how much water pressure is lost as the fluid flows through the pipe. The pressure loss depends on the length of the pipe which is often measured in miles. One formula that is sometimes used to calculate pressure loss requires thatthe pipe length be input in feet. Therefore, it is necessary to be able to convert miles to feet. In other situations you may be forced to work between the SI and U S Customary measurement systems. Say, for example, that as a U S company, your product is manufactured and produced based on U S Customary units. However, a European company would like a proposal to incorporate your system into their existing assembly line, the characteristics of which are based on SI units. You must be able to convert between the two systems in order to provide a proposal for a design which includes your company’s U S product.In this activity you will convert measurements among units in both the U S Customary System and the SI system, and you will convert quantities between the two systems of measurement. You will also gain experience with converting units among units that are not specific to one measurement system (such as people and tanks of water) and use the skills you learn to solve everyday problems (such as calculating the cost of gas to travel a given distance).

Activity 3.2h Unit Conversion HomeworkComplete each of the following. When a calculation is required, show your work. 1. What conversion factor should be used to convert from Gigaliters to liters?1/1,000,000,0002. Convert each of the following quantities to the indicated units. Use the appropriate number of significant figures to express your answer unless otherwise indicated.a. 0.005098 Megaliters to liters. Record your answer in whole liters.0.005098 x 1,000,000 = 5,098 litersb. 57.2 inches to feet.57.2 / 12 = 4.77 feetc.4 ft – 6 ½ in. to inches. Record your answer in fractional inches.4 x 12 = 48 + 6.5 = 54.5 = 54 ½ inchesd. 6 ft – 9 inches to decimal feet. Record your answer to the nearest hundredth of a foot.9 / 12 = .75 + 6 = 6.75 feete. 935.6 inches to yards. Round your answer to the nearest hundredth of a yard.935.6 / 12 = 77.967 / 3 = 25.99 yardsf.23.5 million nanometers to millimeters 23.5 x 10-6= .0000235 millimetersg. 98.6 inches to meters.98.6 / 12 = 8.2 / 3.28 = 2.51 meters3. The width of a strand of fiber is 19.2 micrometers. If 1500 strands are adhered side by side, how wide would the resulting fabric be if measured in centimeters?
