When setting up the conversion, worry about one unit at a time, for example, convert the pound units to gram units, first: Next, convert in 2 to cm 2. Set up the conversion without the exponent first, using the conversion factor, 1 in = 2.54 cm. Since we need in 2 and cm 2, raise everything to the second power: Updated on October 04, 2019 Unit conversions are important in all sciences, although they may seem more critical in chemistry because many calculations use different units of measurement. Every measurement you take should be reported with the proper units.

Here is what we would have gotten: 3.55 m × 1 m 100 cm = 0.0355m2 cm 3.55 m × 1 m 100 c m = 0.0355 m 2 c m. For the answer to be meaningful, we have to construct the conversion factor in a form that causes the original unit to cancel out. Figure 2.6.1 2.6. 1 shows a concept map for constructing a proper conversion. Basic Conversion Cheat Sheet • Three basic units of measurement length, mass (weight), volume o The basic unit of length is: METER o The basic unit of volume is: LITER o The basic unit of mass (weight) is: GRAM • The following are some of the prefixes for the metric system. They are based on 1, 000 ms 1 s or 1 s 1, 000 ms. To convert 18 ms to seconds, we choose the conversion factor that will cancel out milliseconds and introduce seconds. The conversion factor on the right is the appropriate one. We set up the conversion as follows: 18ms × 1 s 1, 000 ms = 0.018 s. Step 2: Calculate. 4.3cm × 1 m 100cm × 106 μm 1 m = 43, 000μm 4.3 cm × 1 m 100 cm × 10 6 μ m 1 m = 43, 000 μ m. Each conversion factor is written so that the unit of the denominator cancels with the unit of the numerator of the previous factor.

FACTORS FOR UNIT CONVERSIONS Quantity Equivalent Values Mass 1 kg = 1000 g = 0.001 metric ton = 2.20462 lbm = 35.27392 oz 1 lbm = 16 oz = 5 x 10‐4 ton = 453.593 g = 0.453593 kg Length 1 m = 100 cm = 1000 mm = 106 microns (µm) = 1010 angstroms (Å) English units. lb = pound Ounce vs Fluid Ounce: oz is a mass unit and fl oz is a volume unit in the English system. oz = ounce pt = pint qt = quart Solution. Multiply the given volume with the conversion factor that has volume in the denumerator, i.e., \ (frac {m} {v} to get the mass desired. 10.0 mL × 0.7893 g 1 mL = 7.89 g 10.0 m L × 0.7893 g 1 m L = 7.89 g. Note that 1mL is exact, and 10.0 and 0.7893 are inexact numbers with 3SF and 4 SF, respectively. Footnotes 1 Strictly speaking, the ounce and pound are units of weight, W (a force equal to the product of mass and gravitational acceleration, W = mg). The conversion relations in this table are commonly used to equate masses and weight assuming a nominal value for g at the surface of the earth.

SI unit: kilogram (kg) The kilogram is defined as being equal to the mass of the International Prototype of the Kilogram (manufactured in 1799). SI unit: pascal (Pa) The pascal is a derived from other units. 1Pa = 1 kg m ⋅ s2 (1) (1) 1 P a = 1 k g m ⋅ s 2. SI unit: kelvin (K) The kelvin is.

Several of the most commonly needed English-metric conversion factors are listed in Table 8.1 on the next page. Because the English inch is defined as 2.54 cm, the number 2.54 in this value is exact. The numbers in the other conversion factors in Table 8.1 are not exact. 2. Table A.2 in Appendix A shows some useful English-English conversion.
