##### This is a free online hex calculator online that converts hex values into bytes, ints, and floats of different bit significance. With millions of different sensors and devices that will be connected to the cloud for IIoT, determining the Endian of the communication protocol is required to read proper values by the SCADA / IIoT server.

- The Hex-To-ASCII output will convert all Hex data into ASCII
- Hex-To-Binary will generated a binary string based on the hex string provided
- Hex-To-Float performs 4 conversions to each one of the 4 Endian Combinations
- Hex-To-UINT (Unsigned Integer) and Hex-To-INT (Singed Integer) Converts the Hex string to the 4 different Endian Combinations.
- We also perform to 16 bit conversions, Hex-To-UINT16 (16 bit Unsigned Integer) and Hex-To-INT16 (16 bit Signed Integer)

When interfacing with new hardware, it is sometimes difficult to determine the number format of a string of raw binary data.

For industrial programmers and field technicians, looking at the communication data in byte format would show an array of bytes that could be difficult to translate into readable text or values.

The complexity is compounded by having to deal with Bit Endians and byte significance. SCADACore’s Hex Converter will relieve some of the confusion with interfacing unknown devices.

### Decimal to hex conversion result in base numbers

## Decimal System

**The decimal numeral system** is the most commonly used and the standard system in daily life. It uses the number 10 as its base (radix). Therefore, it has 10 symbols: The numbers from 0 to 9; namely 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9.

As one of the oldest known numeral systems, the **decimal numeral system** has been used by many ancient civilizations. The difficulty of representing very large numbers in the decimal system was overcome by the Hindu–Arabic numeral system. The Hindu-Arabic numeral system gives positions to the digits in a number and this method works by using powers of the base 10; digits are raised to the n^{th} power, in accordance with their position.

For instance, take the number 2345.67 in the decimal system:

- The digit 5 is in the position of ones (10
^{0}, which equals 1), - 4 is in the position of tens (10
^{1}) - 3 is in the position of hundreds (10
^{2}) - 2 is in the position of thousands (10
^{3}) - Meanwhile, the digit 6 after the decimal point is in the tenths (1/10, which is 10
^{-1}) and 7 is in the hundredths (1/100, which is 10^{-2}) position - Thus, the number 2345.67 can also be represented as follows: (2 * 10
^{3}) + (3 * 10^{2}) + (4 * 10^{1}) + (6 * 10^{-1}) + (7 * 10^{-2})

## Hex System

**Hex**, or *hexadecimal*, is a number system of base 16. This number system is especially interesting because in our casually used decimal system we have only 10 digits to represent numbers. As hex system has 16 digits, the extra needed 6 digits are represented by the first 6 letters of English alphabet. Hence, **hex** digits are 0,1,2,3,4,5,6,7,8 and 9 A, B, C, D, E, F. This number system is the most commonly used in mathematics and information technologies. I.e. in html programming colors can be represented by a 6-digit *hexadecimal number*: FFFFFF represents white, 000000 represents black, and so on.
