Once you are comfortable with this process, you can combine the whole process into a couple quick steps: Write the initial prefix and the final prefix as powers of Divide the initial power of 10 by the final power of To do this, subtract the final exponent from the initial exponent. Multiply your initial value by this answer. Example: How many centilitres cL are in 85 millilitres mL? Optionally, write this in scientific notation : 8. Divide 60 minutes by 13 minutes. That's 4. Multiply that by 16 km: 4.
That means that if a car travels 16 km in 13 minutes, at the same speed it would travel The car is traveling at Yes No. Not Helpful 1 Helpful 2. Include your email address to get a message when this question is answered.
By using this service, some information may be shared with YouTube. You probably don't need to memorize prefixes larger than giga- or smaller than nano-. Those are rarely used except in specific fields of study. Helpful 2 Not Helpful 0. Submit a Tip All tip submissions are carefully reviewed before being published. Remember which "direction" you are going! Check your answers against reality, if possible. Helpful 1 Not Helpful 0. You can only use this method if the base units are the same.
Converting between kilograms and pounds, for example, requires a different formula. Related wikiHows How to. How to. About This Article. Co-authored by:. Co-authors: You might have put the wrong half of the fraction on top. For example, if you multiplied 2 inch. You realize the inches will cancel if you flip the fraction, so you try again with 2 inch x 2.
Method 2. Write down your problem. Figure out exactly what the problem is asking, and write it as a math problem. Here's an example: If a bicycle is moving 10 miles per hour, how many feet does it travel in one minute?
Find the conversion for one unit. Remember, you can only convert between two units that measure the same thing. In our example, we have units that measure length miles and feet , and units that measure time hours and minutes.
Start with one pair and find the conversion between them. Multiply your number by the conversion fraction. Just as describe in the section above, we can write the conversion as a fraction to cancel out units.
Make sure to include every unit in your calculations. Cancel out your units. One of your units should be on the top and the bottom, so you can cancel them. You aren't done yet, but you're getting closer. Multiply with another conversion fraction the same way. Choose a unit that hasn't been converted, and write down the conversion as a fraction.
Remember to arrange the fraction so the units will cancel out during multiplication. In our example, we still need to convert hours to minutes. Cancel units. Another unit should cancel out, just as it did before. Repeat until the conversion is done. If your answer is in the units you were trying to convert to, you're done with the problem. If you're not there yet, convert another unit with the same method.
Once you're used to this method, you can write all the conversions on one line. Method 3. Understand the metric system. The metric system, also called the decimal system, is designed for easy conversion.
To convert from one metric unit to another, you only have to work with round numbers: 10, , , and so on. Learn the prefixes. Metric unit of measurements use prefixes to show how big or small the measurement is. Here's an example with units of weight, but all other metric units use the same prefixes. Use the prefixes in conversion. If you know the prefixes, you don't need to look up the conversion every time you need to convert.
The prefixes already tell you the conversion. To convert from grams to milligrams: milli means. Move the decimal point instead of doing calculations. Example 2: Convert one cubic foot to cubic inches. A cubic foot is a cube with a side length of one foot. Subjects Near Me. Download our free learning tools apps and test prep books. Varsity Tutors does not have affiliation with universities mentioned on its website. If you wanted to convert 14 terabytes to the number of bytes, you would multiply 14 by 1, four times first to convert to GB, then to MB, then to KB, and finally to bytes.
Here is a diagram that summarizes this:. A byte block is exactly what it sounds like: bytes of data. Once you have converted the byte-blocks in to either kilobytes or bytes, you can then easily convert them to whatever other unit you need. Converting between size units is much easier than most people think.
All you need to do is memorize the number 1, and a couple of other rules and you will be on your way to being able to quickly and easily convert between any size units.
We have bumped it as part of our ThrowbackThursday initiative. This post will cover a very simple and easy way to quickly convert between any of these units.
