information clearly. This system of measurement is called the International System of Units (SI). Metric measurement is based on the number ten and makes calculations with the system relatively easy. By using the following conversion chart, converting from one unit to another is done simply by moving the decimal point:
CHEMISTRY 11 SI system practice worksheet: For each question, maintain the same number of Significant Figures in your answer. 1. Convert each of the following measurements to metres: a) 431.5 Em b) 9.875 fm c) 14.587 mm 2. Convert each of the following measurements to litres: a) 182 mL b) 0.895 ML c) 10 µL 3.
Unit Conversion Practice Worksheet For questions 19, be sure to include units in your answers! 1. Example: How many grams are in 1 kilogram? 1000 grams 2. How many grams are in 1 milligram? 3. How many meters are in 1 megameter? 4. How many meters are in 1 centimeter? 5.
Example: 1 mg = 10-3 g; 1 kg = 103 g. Enter 103 in your calculator by typing 1 E 3 (using a button labeled E, EE, or EXP). Check your work: as the unit gets larger, the number should get smaller, and vice-versa. Give all answers in scientific notation. Practice setting these up as dimensional analysis conversions with cancelling units.
There are seven SI base units: second, meter, kilogram, Kelvin, mole, ampere, and candela. Prefixes are added to the SI units because they extend the range of possible
smaller or larger? Explain your answer. Metric System In chemistry we measure matter using SI units. This is an abbreviation for System International. SI BASE UNITS (AKA Base Units): **If you forget, use Tables C and D in your Reference Tables! *Example: In the word kilometer, the root word (base unit) is “meter” and the prefix is “kilo.”
Give all answers in scientific notation. A. Conversions to and from base unit (no prefix). (Problem-solving hint: convert the initial number into scientific notation first, then modify the power of 10 in the correct direction. Remember as the unit gets smaller, the number gets larger and vice-versa.) 1. Convert 4.0 cm to m. c = 10 −2 so 4.0 ...
