Suppose you wish to convert pressure of 14 lb/in 2 to g/cm 2. 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. 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. 1: Chemistry, Matter, and Measurement 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 gal = gallon 8 fluid oz = 1 cup 2 cups = 1 pt 2 pt = 1 qt 4 qt = 1 gallon 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.

Unit converters (aka unit calculators) are tools that allow to convert between different units of measurement for the same quantity. This is the most complete collection of unit converters with 39 different physical quantities supported. Click on a quantity name above to access the unit converter. A set unit of prefixes have been established and are known as the SI prefixes or the metric prefixes (or units). The prefixes indicate whether the unit is a multiple or a fraction of the base ten . It allows the reduction of zeros of a very small number or a very larger number such as 0.000 000 001 meter and 7,500,000 Joules into 1 nanometer. 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. 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

Convert 4.352 micrograms to megagrams. English‑Metric Conversions. English units. 2. are still common in some countries, while people in other countries (and the scientific community everywhere), use metric units almost exclusively. Unit analysis provides a convenient method for converting between English and metric.
