The metric system is actually easier to use than the English system, as you will see shortly.

The metric system uses prefixes to indicate the magnitude of a measured quantity. The prefix itself gives the conversion factor. You should memorize some of the common prefixes, as you will be using them on a regular basis. Common prefixes are shown below:. Start with what you know and let the conversion factor units decide how to set up the problem. If a unit to be converted is in the numerator, that unit must be in the denominator of the conversion factor in order for it to cancel.

Notice how the units cancel to give grams. If you don't know how to use the scientific notation on your calculator, try to find out as soon as possible. Look in your calculator's manual, or ask someone who knows. Also, notice how the unit, mg is assigned the value of 1, and the prefix, milli- is applied to the gram unit.

Next, let's try a more involved conversion.

Length Converter

Suppose you wanted to convert mg to kg. You may or may not know a direct, one-step conversion. In fact, the better method foolproof to do the conversion would be to go to the base unit first, and then to the final unit you want. In other words, convert the milligrams to grams and then go to kilograms:.

In this example, a quantity has been converted from a unit for volume into other units of volume, weight, amount in moles, and number of atoms. Every factor used for the unit conversion is a unity. The numerator and denominator represent the same quantity in different ways.

Even in this simple example, several concepts such as the quantity in moles, Avogadro's number, and specific density or specific gravity have been applied in the conversion.

If you have not learned these concepts, you may have difficulty in understanding some of the conversion processes. Identify what you do not know and find out in your text or from a resource.

Some years ago, most people believed that 10 seconds to dash a meter race was the lowest limit. For comparison, the two speeds must be expressed in the same unit. Note: a different unit can be selected for the comparison e. These conversions are accomplished in the same way as metric - metric conversions.It is often necessary to convert from one unit to another.

For example, if you are reading a European cookbook, some quantities may be expressed in units of liters and you need to convert them to cups. Or perhaps you are reading walking directions from one location to another and you are interested in how many miles you will be walking. In this case, you may need to convert units of feet or meters to miles. Suppose we want to convert 80 m to kilometers.

The first thing to do is to list the units you have and the units to which you want to convert. In this case, we have units in meters and we want to convert to kilometers. Next, we need to determine a conversion factor relating meters to kilometers. A conversion factor is a ratio that expresses how many of one unit are equal to another unit. For example, there are 12 in. Refer to Appendix B for a more complete list of conversion factors. In this case, we know that there are m in 1 km. Now we can set up our unit conversion.

We write the units we have and then multiply them by the conversion factor so the units cancel out, as shown:.

1.4: Unit Conversion

Note that the unwanted meter unit cancels, leaving only the desired kilometer unit. You can use this method to convert between any type of unit.

Now, the conversion of 80 m to kilometers is simply the use of a metric prefix, as we saw in the preceding section, so we can get the same answer just as easily by noting that. However, using conversion factors is handy when converting between units that are not metric or when converting between derived units, as the following examples illustrate. The distance from the university to home is 10 mi and it usually takes 20 min to drive this distance.

Note : Average speed is distance traveled divided by time of travel. First we calculate the average speed using the given units, then we can get the average speed into the desired units by picking the correct conversion factors and multiplying by them. The correct conversion factors are those that cancel the unwanted units and leave the desired units in their place.

In this case, we want to convert miles to meters, so we need to know the fact that there are m in 1 mi. We also want to convert minutes to seconds, so we use the conversion of 60 s in 1 min. Light travels about 9 Pm in a year.

Given that a year is about 3 x 10 7 s, what is the speed of light in meters per second? The density of iron is 7. We need to convert grams to kilograms and cubic centimeters to cubic meters. The idea is still to multiply by the conversion factors in such a way that they cancel the units we want to get rid of and introduce the units we want to keep. We know from Figure 1. What is that in square kilometers that is, km 2? Try doing this both by converting 10 7 m to km and then squaring it and then by converting 10 14 m 2 directly to square kilometers.

You should get the same answer both ways. Unit conversions may not seem very interesting, but not doing them can be costly. One famous example of this situation was seen with the Mars Climate Orbiter. On September 23,while attempting to guide the probe into its planned orbit around Mars, NASA lost contact with it.This shows initiative and a dedication to his job.

Unit Conversion & Significant Figures: Crash Course Chemistry #2

Arranged a self drive tour of Iceland through Nordic Visitor (Iceland Complete Tour). Was very impressed with the quality of service. Accommodations, Vehicle rental etc was of excellent quality. The biggest initial reason for using Nordic Visitor was the quality of their web site.

It is very detailed and informative. Their staff responded well and quickly to any questions and concerns we had. Am looking to do a self drive tour of Norway and Nordic Visitor will be my first choice as my travel agent.

We were very pleased with the quality and location of our accommodations. There was a good amount of time to make our transportation connections. We never felt rushed. All in all, we were very satisfied with Nordic Visitor. I travel a great deal, all over the world (4-5 times abroad per year for holidays). I normally always do ALL the arrangements myself (flights, hotels, rental cars, tours etc. However, for personal reasons I didn't have time to organize a 3 week tour in Norway myself this year, so after a bit of googling and contacting some local travel agents as well (I live in Switzerland), I decided to go with Nordic Visitor and have the absolutely lovely young travel agent Kolbrun, do everything for us.

She put together a custom-made tour for us based on all my wishes (I'm very demanding) and then gave me lots of ideas and suggestions as well. The hotels we stayed in were brilliant.
