CHEM 107 Lecture Notes - Lecture 2: International System Of Units, Ampere, Dimensional Analysis
Document Summary
The answer contains the same number of sig figs as there are in the measurement with the fewest sig figs. 9. 2 x 6. 8 x 0. 3744 = 23. 4225 reduced to 23 because we can only have. The answer has the same number of decimal places as there are in the measurement with the fewest decimal places. They do not limit the number of significant digits in a calculation. A conversion factor is a ratio of equivalent quantities used to express a quantity in different units. 1 i/5280ft = in 1 mile, there are 5280 feet or one mile per 5280 feet. 5280 ft/ 1 mi = in 5280 feet, there is one mile. A conversion factor is chosen and set up so that all units cancel except those required for the answer. Electric current kilogram kg meter second kelvin ampere m s. Exponents always go with the base unit 1 nanosecond = 10^ -9 seconds tera.
