<p class="center"><b>Measurement</b> is finding a number that shows the size or amount of something.</p>
|
|
<p>We can measure:</p>

<p style="float:right; margin: 0 0 5px 10px;"><img src="images/guitar-length.jpg" alt="guitar length" height="172" width="259"></p>
|
|
<p class="larger">Length</p>
|
|
<p>Length is how far from end to end. Also called Distance.</p>
|
|
<p>The length of this guitar is about <a href="metric-length.html">1 meter</a> (slightly more than <a href="us-standard-length.html">1 yard</a>).</p>
|
|
<p> </p>

<p style="float:left; margin: 0 10px 5px 0;"><img src="images/squaremeter.jpg" alt="dog inside square meter" height="195" width="294"></p>
|
|
<p class="larger">Area</p>
|
|
<p>Area is the size of a surface: how much is inside the boundary of a flat (2-dimensional) object such as a triangle or circle.</p>
|
|
<p>Here Ariel the Dog is waiting patiently inside <a href="metric-length.html">1 square meter</a>.</p>

|
|
<p class="larger">Volume</p>
|
|
<p>Volume is the amount of 3-dimensional space an object occupies. Also called Capacity.</p>
|
|
<p>This jug has exactly <a href="metric-volume.html">1 liter</a> of water in it (slightly more than <a href="us-standard-volume.html">2 pints</a>)</p>
|

|
|
<p class="larger">Mass (Weight)</p>
|
|
<p>Mass is how much matter something contains.</p>
|
|
<p>This bar of Gold has a Mass of <a href="metric-mass.html">1 kilogram</a> (slightly more than <a href="us-standard-mass.html">2 pounds</a>)</p>
|
|
<p>(Weight is "Heaviness" ... the downward force caused by gravity on an object.)</p>

|
|
<p class="larger">Temperature</p>
|
|
<p>How hot or cold a thing is.</p>
|
|
<p>Temperature is measured using a thermometer, usually in the Celsius or Fahrenheit scale.</p>
|
|
<p>This block of ice would measure 0° <a href="../temperature-conversion.html">Celsius</a>, or 32° Fahrenheit</p>

|

|
<p class="larger">Time</p>
|
|
<p>Time is the ongoing sequence of events taking place.</p>
|

<p>We measure time using seconds, minutes, hours, days, weeks, months and years.</p>

<h2>Systems of Measurement</h2>
|
|
|
|
<p>There are two main "Systems of Measurement":</p>
|
|
<p class="dotpoint"><a href="metric-system-introduction.html">Metric System</a> (meters, kilograms, liters, etc.)</p>
|
|
<p class="dotpoint"><a href="us-standard-units-introduction.html">US Standard Units</a> (feet, pounds, pints, etc.)</p>
|
|
|
|
|
|
|
|
<h2>History of Measurement</h2>
|
|
|
|
<p>Years ago people came up with standard length measures,
|
|
but they didn't all agree on one system.</p>
|
|
<p>The Imperial System (which uses yards, feet, inches, etc
|
|
to measure length) was developed over hundreds of years in the
|
|
UK</p>
|
|
<p>Then the French came up with the <a href="metric-system.html">Metric System</a> (origins in
|
|
1670, but developed in the 1790s), which soon spread through Europe, and then most of the world, even to England itself
|
|
in 1965.</p>
|
|
<p>The USA developed their own version of the Imperial system (<a href="us-standard-units-introduction.html">US Standard Units</a>), but the Metric System is also used in the USA, particularly in Science.</p>
