Convert bit to byte - Conversion of Measurement Units

How to convert Bits to Bytes To convert from bits to bytes, simply divide the number of bits by 8. For example, bits are equal to / 8 = 32 bytes. You can see more example calculations and a conversion table below. The main non-SI unit for computer data storage is the byte. 1 bit is equal to byte. Note that rounding errors may occur, so always check the results. Use .

The term "byte" was first used to describe an 8-bit block in a paper by Werner Buchholz [3] and went into widespread usage ever since, serving as the basis for other units such as the KiloByte, MegaByte, GigaByte and so on. There were attempts to use bit "bytes", but they did not receive adoption. Both the bit and the byte are data units used for measuring data storage capacity and transmission capacity bandwidth.

The only difference between the two is that a byte is 8 times larger than a bit. A bit is the smallest possible amount of data in a binary computing system - practically all computers, laptops, phones, smartphones, robots, cars, etc. Its value can be either one or zero, corresponding to a wire with electrical current running through it or not. Both the bit and the byte are used mainly by computer programmers, database architects and the like, where they are relevant.

The average user usually deals with data in much greater quantities, where units such as the megabyte MBgigabyte GB and terabyte TB are much more convenient to use. To convert from bits to bytes, simply divide the number of bits by 8.

How to convert bits to Bytes: Enter a value in the bits field and click on the "Calculate Bytes" button. Your answer will appear in the Bytes field. Your answer will appear in .

You can also learn how to translate binary to decimal and back using hexadecimal as a stepping stone between the two number forms.

Computer technology uses voltage to represent binary using voltage levels since it is easy for digital logic to detect a high or low voltage. On its own a bit is not much use but combine several bits and use a little maths and you have a useful way of representing numbers. Binary numbers are represented positionally in the same way that normal decimal numbers are represented. Each bit in a byte represents a higher value depending on its position within the byte.

The difference between a bit and a byte is simply that a byte is made up of several bits there are 8 bits in a byte - in the past a byte could be 5, 6 or even 9 bits long. You already know but is is useful to understand the construction of a decimal number so that you can understand binary numbers. As you move to the left the position tells you what multiplier to use for the digit and for decimal it is in powers of The base or radix of the decimal system is 10 meaning that there are 10 different symbols used to describe any decimal number:.

This concept is used to let a computer do mathematics by using the same positional system but using binary, as this is the only language a computer understands! A byte is simply a group of eight bits with the position of each bit determining its contribution to the total value. Bytes usually have 8 bits with the highest value the left and the lowest value to the right in the same way as a normal decimal number. Again the number is represented by position - as you move to the left, the multiplier is increased by a power but this time it is a power of two as the base of the number is 2.

So, you can change the 8 bit into a byte fairly easily but see later for a simpler method that uses three calculations not eight. For each bit position you need to figure out if the bit adds to the total value has a bit value of 1 or does not add to the total has a bit value of zero.

Starting with the highest bit position value you divide the number by the bit position value. If the result is greater or equal to 1 then it contributes. Here's an example:. So the binary number is : you have converted the binary number from a bit into a byte using 16 calculations! See later for a simpler method that uses three calculations not 16 for the same bit to byte conversion.

All of that division, multiplication and subtraction is much too much work - imagine having to convert numbers that are 16 bits long 32, even 64 bits long. Of course easiest way is to use a software calculator program or a calculator that lets you work in hexadecimal or binary and let it do the conversion.

Note you can find a convenient bit to byte two nibbles conversion table here. This method of bit to byte conversion steps around the binary calculation by using hexadecimal as an intermediate step between decimal and binary - you don't need to do a calculation for each bit - it is basically divide and conquer method and you'll probably learn something about number representation as well.

Taking the example in a previous section : binary. Bit to byte conversion of a binary number. So instead of doing 8 calculations you do three and you can do these quickly on paper or with a standard calculator. Basically, to do a bit to byte conversion, you take an 8 bit binary number and form it into groups of 4 bits nibbles. You then translate each nibble into a hexadecimal number a 2 hex digit byte using this table.

You then multiply the left digit by 16 and add the result to the first digit. Hexadecimal is used as it is simple to translate from binary and is convenient when writing it down especially for longer binary numbers. Note see later for converting larger numbers. This is the opposite of the previous bit to byte conversion.

Taking the example in a previous section : decimal. So instead of doing 16 calculations you do three and you can do these quickly on paper or with a standard calculator. Basically you take the number, divide it by 16 and use the whole part as the left digit and use this table to translate it to a hex character or see the table later on. Subtract 16 times the whole part from the original number giving you the right digit. Translate this to a hex character.

Now translate both hex values to binary using the table and you have the final binary result. To easily convert binary numbers to decimal you need to use an intermediate number form - hexadecimal.

This is a number having base 16 and is closely related to binary as it shares some of the same power values. You can see that there are 2 hex digits for every 8 binary digits. This immediately says that using hexadecimal reduces the number of digits and therefore the number of calculations needed i. Base 16 or hexadecimal uses 16 digits to represent a number - in the same way that base 10 decimal uses ten digits and base 2 binary uses two digits.

So what symbols do you use for hexadecimal - well you need six more digits. I have been using hexadecimal for years. You could use any symbols you want but the conventional system is to use:. So what are the hexadecimal values. This is basically the same method but scaled up with a simple twist. All you do is split the 16 bit value into two 8 bit values with the same calculations as for the 8 bit values.

The left value is scaled by and that's it. An example For the binary value binary. This process is nearly the same as the 8 bit conversion but just uses two bit to byte conversions. For the decimal value This process is the opposite of the bit to byte conversion and uses two byte to bit conversion. Back to the home page from the bit to byte page. Arduino oversampling is a technique to increase ADC resolution by reading more samples then decimating.
