 Conversion to SI Units: (HINT: THE CONVERSION TABLE WOULD BE VERY USEFUL HERE)A. What are the SI units for these: Length Mass Time Temperature B. Convert these length units to SI units: 2156 cm 2.48 yards 67.2 in 2 miles C. Convert these masses to SI units: 2000 g 4 lbs 0.692 torr D. Convert these temperatures to SI units: 26oF 24oC A. meters kilograms seconds kelvin B. Remember what I said in the tutorial about multiplying and dividing? You must divide the original units with the original units, with the new units on top. In the first step, the 1 inch is the new unit, and the cm is the old unit. The cms cancel out when you multiply them together (simple algebra) 2156 cm * (1 inch/2.54 cm) * (1 meter/39.37 inches) = 21.56 meters 2.48 yards * (1 meter / 1.094 yards) = 2.27 meters 67.2 in * ( 1 meter / 39.37 in) = 1.71 meters 2 miles * (1609 meters / 1 mile) = 3218 meters C. 2000 g * (1 kg / 1000g ) = 2 kg 4 lb. * (0.4536 kg/ 1 lbs) = 1.18144 kg 0.692 ton * (2000 lbs / 1 ton) * (0.4536 kg / 1 lbs) = 627.8 kg D. C = (5/9)(F - 32) = (5/9)(26-32) = -3.33oC + 273 = 269.667 K 46oC + 273 = 318 K
