SI Prefixes: When setting up a conversion factor to or from a base unit, use 1 for the prefixed unit and the power of 10 in front of the base unit. 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).
A prefix is something that goes in front of a unit and acts as a multiplier. This sheet will give you practice at converting figures between prefixes. (3)! Complete the table, below: (4)! Convert the figures into the prefixes required.
SI Units Scientists all over the world use the same system of units so they can communicate 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.
The Prefixes. Conversion. Bits and Bytes. Practice Answers. Resources and Going Further. Introduction. Metric Prefixes are incredibly useful for describing quantities of the International System of Units (SI) in a more succinct manner.
Practice Problems for SI Base Units, Prefixes, and Derived Units . Due: Tomorrow beginning of class, if not done in class today. Show ALL work. 1. List the base unit (no prefix needed) that would be used to measure the following things: a. Perimeter of a rectangle . b. Temperature of a liquid during a reaction .
This free quiz helps you practice converting between SI (metric system) prefixes as well as a wide variety of dimensional analysis problems.
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.) Convert 4.0 cm to m.
