Physics I: 501 Practice Problems For Dummies (+ Free Online Practice) When solving physics problems, you'll often encounter unit prefixes that you need to know. You also need to be familiar with common unit symbols and their corresponding SI units. The following tables list some of the typical prefixes and symbols that you may see. Now we can set up our unit conversion. We write the units we have and then multiply them by the conversion factor so the units cancel out, as shown: 80 m × 1 km 1000 m = 0.080 km. (1.4.1) (1.4.1) 80 m × 1 k m 1000 m = 0.080 k m. Note that the unwanted meter unit cancels, leaving only the desired kilometer unit. A conversion factor is an expression for the relationship between units that is used to change the units of a measured quantity without changing the value. A conversion ratio (or unit factor) always equals one (1), where the numerator and the denominator have the same value expressed in different units. 19 In the United States, the cup, tablespoon, and teaspoon are defined as 8, 1/2, and 1/6 fluid ounces, respectively. For practical usage the metric equivalents are 250 mL, 15 mL, and 5 mL. 20 No change in inch-pound U.S. usage is required for time units.

A conversion factor is a ratio that expresses how many of one unit are equal to another unit. For example, there are 12 in. in 1 ft, 1609 m in 1 mi, 100 cm in 1 m, 60 s in 1 min, and so on. Refer to Appendix B for a more complete list of conversion factors. In this case, we know that there are 1000 m in 1 km. Now we can set up our unit conversion. Online calculators for unit conversion.

Length. 1 in = 2.54 cm = 0.0254 m: 1 ft = 30.48 cm = 0.3048 m: 1 yard = 91.44 cm = 0.9144 m: 1 mile = 1.6093 Km =. Comprehensive physics and astronomy online education, research and. Method 1 Moving the decimal three places to the right gives: Method 2 Since you moved three spaces to the left to get to ml on the diagram divide the value by ten to the power of minus three (10-3). 10 -12. 1 picometer (pm) = 10 -12 meters. Femto. f. 10 -15. 1 femtometer (fm) = 10 -15 meters. These base SI units can be combined with any of the prefixes to create units that are most appropriate for what is being measured. For example, you wouldn't measure the distance from LA to New York in meters, the base unit.

In physics, we usually need to convert units from one standard to another, such as mile to meter, hour to second, meter to an inch, feet to meter, kilogram to the gram, and so on. You'll need to know how to convert meter to the inch, a kilometer to a mile, and so on, such as 1m = 39.37in or 1km = 0.6214mi.
