At the end of this chapter, students should be able to:

State basic quantities and their respective SI units and symbols : length (m), time (s), mass (kg), electrical current (A), temperature (K), amount of substance (mol) and luminosity (cd).

State derived quantities and their respective units and symbols: velocity (m s -1 ), acceleration (m s -2 ), work (J), force (N), pressure (Pa), energy (J), power (W) and frequency (Hz).

Perform conversion between SI and British units.

Table shows the conversion factors between SI and British units for length and mass

Conversion of unit 1 angstrom ( ) = 10 10m 1 kg = 0.0685 slug 1 mi = 5280 ft = 1.609 km 1 lb = 0.453 592 kg 1 km = 0.621 mi 1 slug = 14.59 kg 1 in = 2.54 cm 1 kg = 10 3g 1 m = 39.37 in = 3.281 ft Mass Length 19.

Solve the following problems of unit conversion.

a. 15 mm 2= ? m 2 b. 65 km h 1= ? m s 1

c. 450 g cm 3= ? kg m 3 d. 29 cm = ? in

e. 12 mi h 1= ? m s 1

Solution :

a. 15 mm 2= ? m 2

b. 65 km h -1= ? m s -1

Perform conversion between SI and British units.

Learning Outcome: 23. Real-world implications One example of the importance of agreed units is the failure of theNASA Mars Climate Orbiter , which was accidentally destroyed on a mission to theplanet Marsin September 1999 instead of enteringorbit , due to miscommunications about the value of forces: different computer programs used different units of measurement ( newtonversuspound force ). Enormous amounts of effort, time, and money were wasted 24. Real-world implications On April 15, 1999Korean Aircargo flight 6316 fromShanghaitoSeoulwas lost due to the crew confusing tower instructions (in metres) and altimeter readings (in feet). Three crew and five people on the ground were killed. Thirty seven were injured. 25. Real-world implications In 1983, a Boeing 767 (which came to be know as theGimli Glider ) ran out of fuel in mid-flight because of two mistakes in figuring the fuel supply ofAir Canada 's first aircraft to use metric measurements.This accident is apparently the result of confusion both due to the simultaneous use of metric & Imperial measures as well as mass & volume measures. 26.
