Frequently Asked Questions
Everything you need to know about decimal conversions, accuracy, and formulas.
01How do you convert binary to hex (hexadecimal)?▼
To convert binary to hex: 1) Group the binary digits into sets of 4 bits (nibbles) starting from right to left for the integer part, padding the leftmost group with zeros if needed. 2) Convert each 4-bit group into its equivalent hexadecimal digit (0-9, A-F). 3) Combine the hexadecimal digits with the '0x' prefix.
02Why is 4 bits equal to 1 hex digit?▼
Because 2⁴ = 16. A 4-bit binary group has exactly 16 possible states (0000₂ to 1111₂), perfectly corresponding to the 16 hexadecimal digits (0 through F).
03How do you convert fractional binary to hex?▼
For the fractional part after the radix point, group bits into sets of 4 from left to right (padding with trailing zeros if necessary), then replace each 4-bit group with its corresponding hex digit. For example, 0.101₂ = 0.1010₂ = 0.A₁₆.
