Text to Hex Converter

What Is Hexadecimal?

Hexadecimal (or hex) is a base-16 numeral system, widely used in computing and digital systems for its efficiency in representing binary values. Unlike the decimal system, which uses ten digits (0-9), hexadecimal uses sixteen distinct symbols: the numbers 0 to 9 and the letters A to F (or a to f).

In hexadecimal, each digit represents four binary digits (bits), making it particularly useful for succinctly displaying large binary numbers. It's frequently used in programming and computer engineering, especially in contexts where binary values are prevalent, such as memory addresses and color coding in web design.

How to Use the Text to Hex Converter

Enter your ASCII text into the "Input" text box and see the hex conversion in the "Output" box. You can change the delimiter by adjusting the "Delimiter" dropdown and the encoding by adjusting the "Encoding" dropdown.

How It Works

If you entered the word "text", the tool will convert this string into Hexadecimal by converting each ASCII character first to decimal and then to Hexadecimal. For example, the calculation for converting "text" to Hexadecimal is below:

• "t" => 116 = 7×16¹ + 4×16⁰ = 74₁₆
• "e" => 101 = 6×16¹ + 5×16⁰ = 65₁₆
• "x" => 120 = 7×16¹ + 8×16⁰ = 78₁₆
• "t" => 116 = 7×16¹ + 4×16⁰ = 74₁₆

Therefore, "text" in Hexadecimal would be written as the hex bytes: 74 65 78 74.

Common Hexadecimal Conversions

How to Convert '0' to Hexademical?

Look up '0' in the ASCII table which gives 48 as the decimal (base-10) number. Then convert this to Hexadecimal (base-16) which gives 30.

• "0" => 48₁₀ = 3×16 = 3×16¹+0×16⁰ = 30₁₆

How to Convert 'A' to Hexademical?

Look up 'A' in the ASCII table which gives 48 as the decimal (base-10) number. Then convert this to Hexadecimal (base-16) which gives 30.

• "A" = 65₁₀ = 4×16+1 = 4×16¹+1×16⁰ = 41₁₆
