Interactives . British and Metric Conversions . About this Interactive
In the metric system, each basic type of measurement (length, weight, The US English System of measurement grew out of the manner in which people. Introduction. Today it is very important to be able to understand measurements in both the English system of units and the SI (Systems. fengis-ga: The relationship between the metric and 'english' units of measure are as wide-ranging and unique as any relationship defined by.
Learn to convert metric units. Students will learn how to convert metric units from one unit to another within the metric system. For instance, they will have opportunities to practice basic length conversions, including converting meters to centimeters, millimeters, and kilometers, and then back to the original unit again. For mass conversions, students will learn to convert grams to milligrams, and kilograms back to grams.
For volume conversions, students will practice converting kiloliters to liters and liters to milliliters. Learn to convert British units. Student will learn to convert British units from one unit to another within this system. For example, students will practice length conversions, such as inches to feet and yards to miles, and volume conversions, such as cups to pints and quarts to gallons.
Learn to convert British units to metric units. Student will learn to convert units from one system to another-from British to the metric system and then back again.
Conversion of Units
Student will become familiar with equations that can be used to convert various units and will then be given an opportunity to review the equations in interactive exercises. In keeping with the expected knowledge of students in gradesBritish and Metric Conversions will help assess the skills needed to be successful in a math class. In various problem-solving exercises, students will have numerous opportunities to illustrate what they have learned about measurement systems.
Finally, a fun interactive test will provide teachers with a better understanding of each student's strengths and weaknesses with the material. Each section explores one aspect of the relationship between British and metric units and explains how to convert units from one system to the other.
By following the instructions on the screen, students will learn about various subtopics. Students will view animations, read explanations, learn the symbols for various units, and perform computations to convert from one system to the other. Some of these interactive features will help students understand the concepts involved, and some will test how much students have learned. We offer a simple and foolproof method for handling the problem, which will always work if you don't take shortcuts!
We all know that any number multiplied by 1 equals itself, and also that the reciprocal of 1 equals 1.
We can exploit these rather trivial properties by choosing our 1's carefully so that they will perform a unit conversion for us. Suppose we wish to know how many kilograms a pound person weighs. Note that the 1's are dimensionless; the quantity number with units in the numerator is exactly equal to the quantity number with units in the denominator. If we took a shortcut and omitted the units, we would be writing nonsense: Now we can multiply any other quantity by these 1's, and the quantity will remain unchanged even though it will look considerably different.
In particular, we want to multiply the quantity " pounds" by 1 so that it will still be equivalent to pounds, but will be expressed in kg units. But which "1" do we choose? Very simply, if the unit we want to "get rid of" is in the numerator, we choose the "1" that has that same unit appearing in the denominator and vice versa so that the undesired units will cancel. Hence we have Note that you do not omit the units, but multiply and divide them just like ordinary numbers. If you have selected a "well-chosen" 1 for your conversion your units will nicely cancel, which will assure you that the numbers themselves will also have been multiplied or divided properly.
That's what makes this method foolproof: Strictly speaking, this is not really incorrect: As a passenger on the Space Shuttle, you note that the inertial navigation system shows your orbital velocity at 7, meters per second. You remember from your astronomy course that a speed of 17, miles per hour is the minimum needed to maintain an orbit around the Earth.

Should you be worried? Because of your careful analysis using "well-chosen 1's", you can conclude that you will probably not survive long enough to have to do any more unit conversions.
