How To Convert Between Units Using Conversion Factors Dummies Dimensional analysis (unit conversions) involves the use of conversion factors that will cancel unwanted units and produce the appropriate units. 1.2.2: problem solving and unit conversions is shared under a license and was authored, remixed, and or curated by marisa alviar agnew & henry agnew. during your studies of chemistry (and physics also. 1 l = 1000 ml. 1 ft = 30.48 cm. 1 pt = 473.2 ml. 4.9 ml = 1 tsp. 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). for example, a basketball player’s vertical jump of 34 inches can be.

Conversions And Constants Chemistry Libretexts Unit conversions work the same way, except "1" is expressed in the form of a conversion factor or ratio. consider the unit conversion: 1 g = 1000 mg. this could be written as: 1g 1000 mg = 1 or 1000 mg 1 g = 1. if you multiply a value times either of these fractions, its value will be unchanged. For example, to convert 2.77 kg to milligrams: 2.77kg × 1000g 1kg = 2770g (convert to the base units of grams) 2770g × 1000mg 1g = 2770000mg = 2.77 × 106mg (convert to desired unit) alternatively, it can be done in a single multi step process: 2.77 kg × 1000 g 1 kg × 1000mg 1 g = 2770000mg =(2.5.2). Therefore, the exact relationship of btu to joules and other energy units depends on the temperature at which btu is measured. 59 °f (15 °c) is the most widely used reference temperature for btu definition in the united states. at this temperature, the conversion factor is the one provided in this table. ↵.
