The method for converting between units works the same as the one for converting units of area and volume. When you are converting one sort of unit to another, you need to know how many smaller units are needed to make ({1}) larger unit. For example: [& (1~km^ {2} = 1~km times 1~km) [1,000~m times 1,000~m] [1,000,000~m^ {2}]&]
How to safely convert from one unit to another?
The important points are:
- Write the conversion as a fraction (that equals one)
- Multiply it out (leaving all units in the answer)
- Cancel any units that are both top and bottom

Why do we convert units?
In order to have accuracy and avoid confusion in measurement, we need to convert one unit to another. For instance, we do not measure the length of a pencil in kilometres.
How do you cancel units in physics?
Unit Cancellation is just a method of converting numbers to different units. Let the units tell you whether you should multiply or divide by a conversion factor. Notice that we put the first conversion factor with miles on the bottom and ft on the top so that miles would cancel out.

Unit Conversion Table
Below is the list of different units and their conversions. To know volume, length, time, energy, area, power, force, mass, viscosity, and density unit conversion refer to the unit conversion table given below.
Solved Problems
Unit conversion is one of the topics that you need to master in order to do well in physics. Here, we have provided a few practice questions to help you better understand the concept.
How to calculate cubic feet?
You would need to get another dimension in feet (such as the depth or height) and multiply that dimension by the square footage to get cubic feet.
What does square mean in units?
If your units measure two different things (like length and weight), you can't convert between them. People often get confused about length, area, and volume, which are three different things. Remember that "square" or " 2 " means area, and "cubic" or " 3 " means volume.
How to cancel out units in math?
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.
How to multiply with another fraction?
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.
What is 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, 100, 1000, and so on. Learn the prefixes. Metric unit of measurements use prefixes to show how big or small the measurement is.
Why do we use prefixes in metric units?
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. The prefixes below are in italics, but you can do most conversions with just the most common one, in bold . Use the prefixes in conversion.
How to write a multiplication problem?
Multiplying these two numbers together will give you your answer. To start this, write out the multiplication problem, with units after each value.
How to convert a base unit to a larger unit?
Convert from a base unit to a larger unit. To convert to a larger unit of measurement, you'll divide by the conversion factor instead of multiplying. As always, you're less likely to make a mistake if you include the units at each point in your calculation: 65 300 metres is equal to.
How to convert kilometres to metres?
Convert kilometres to metres. Since kilo- means 1 000, one kilometre (km) is equal to 1000 metres (m). Multiply the number of kilometres by 1 000 to get the same measurement in metres.
What is the difference between a kilogram and a kilometre?
"Kilo" is one of the most common unit prefixes, so you might already recognize it from words like "kilogram" and "kilometre". This prefix means "1000" (one thousand). Kilo- is abbreviated as "k-", so a kilogram is "kg" and a kilometre is "km ".
How many km does a car travel in 13 minutes?
Divide 60 minutes by 13 minutes. That's 4.615. Multiply that by 16 km: (4.615) (16 km) = 73.84 km. That means that if a car travels 16 km in 13 minutes, at the same speed it would travel 73.84 km in one hour. The car is traveling at 73.84 kph.
How to divide the power of 10?
Divide the initial power of 10 by the final power of 10. (To do this, subtract the final exponent from the initial exponent.)
What is the most common mistake with conversions?
Check your answer. Probably the most common mistake with these conversions is to accidentally divide instead of multiply or vice versa. There are several ways to catch this mistake:
Can SI units be used as prefixes?
These units are almost always seen in their base form, but they can use SI prefixes.
How many meters are in a kilometer?
A kilometer has 1000 meters, and an hour has 3600 seconds, so a kilometer per hour is:
How many m is 3 km?
So, 3 km equals 3000 m. Well we knew that, but we want to follow a system, so that when things get harder we know what to do!

What is the point marked 1 particle per m2 second?
The point marked "1 particle per m 2 -second" has f ( θ, ϕ, E) ≈ 10 − 1 m − 2 s − 1 sr − 1 GeV − 1. If we multiply by 4 π (assuming the flux is isotropic) and a bin width of 1 GeV, then we get the right flux.
How to get f from histogram?
To obtain f ( θ, ϕ, E) from a histogram, you divide the counts in each bin by the bin width. Conversely, if you have the so-called differential flux f ( θ, ϕ, E) and want to know how many counts to expect in a histogram bin at some energy, you simply multiply it by the bin width.
Is energy scaled?
So, unless I've misunderstood your question, that energy is just a scaling for the plots. Similar to how figure 9 of that paper is scaled by 10 − 24.
