What is the diameter in centimeters? When we multiply a quantity (such as distance given in inches) by an appropriate unit conversion factor, we convert the quantity to an equivalent value with different units (such as distance in centimeters). 1.80 x 10^3 kg Great question! I know this is a really dumb question, but I just need a clarification I guess. For example, a basketball players vertical jump of 34 inches can be converted to centimeters by: \[\mathrm{34\: \cancel{in.} She is required pay $3,500 (in US dollars) per year to the university, however, she must pay in euros. Now let's try to apply this formula. If you want to check whether a given equation is correct or not, you can compute the dimensions on both sides (LHS and RHS), if both dimensions are equal, then the equation is correct, otherwise, it's wrong. Questions include m/s to mph, liters to cups, and pounds to kilograms. It might jump out of you, well, if we can get rid of this hours, if we can express it in terms of seconds, then that would cancel here, and we'd be left with just the meters, which is a unit of distance Your dashboard will track each student's mastery of each skill. To mark a scale on a thermometer, we need a set of reference values: Two of the most commonly used are the freezing and boiling temperatures of water at a specified atmospheric pressure. \hline \text { Mar. seconds, they give it in hours, so they say the time is equal to 1 hour. She knows that 1.00 mol of the gas occupies a volume of 24.5 L at the set temperature and pressure. (F) Add 5 to each side of the equation. State true or false: dimensional analysis helps to know if the physical quantity is a vector or a scalar quantity. The only container readily available is a 150-mL Erlenmeyer flask.
