For example, a basketball player’s vertical jump of 34 inches can be converted to centimeters by: [latex]\text{34 in. Then, [latex]\text{density}=\frac{\text{4.20}\times {10}^{3}\text{g}}{3.78\times {10}^{3}\text{mL}}=\text{1.11 g/mL}[/latex]. Use dimensional analysis to convert the measurements. A 4.00-qt sample of the antifreeze weighs 9.26 lb.

Write down given number and unit 2.) The trick is to decide what fractions to multiply. . Consequently, converting a temperature from one of these scales into the other requires more than simple multiplication by a conversion factor, m, it also must take into account differences in the scales’ zero points (b).

What are the corresponding temperatures on the Celsius and kelvin temperature scales? We use the word temperature to refer to the hotness or coldness of a substance. (This is a very common conversion.) Answer key. Every time you need to convert from one unit to another, you need to focus on finding the appropriate series of conversion factors that can be used to convert between the two units. Again, arithmetic on the numbers (25/10 = 2.5) was accompanied by the same arithmetic on the units (m/m/s = s) to yield the number and unit of the result, 2.5 s. Note that, just as for numbers, when a unit is divided by an identical unit (in this case, m/m), the result is “1”—or, as commonly phrased, the units “cancel.”. Convert 27 km/hr into m/s. Convert 42.3 cm to m. 3em 2. The freezing temperature of water on this scale is 273.15 K and its boiling temperature 373.15 K. Notice the numerical difference in these two reference temperatures is 100, the same as for the Celsius scale, and so the linear relation between these two temperature scales will exhibit a slope of [latex]1\frac{\text{K}}{^{\circ}\text{C}}[/latex] . 1.
