  Binary Calculator

  technology

  Bitwise AND, OR, XOR, NOT, SHIFT and base conversions for binary.

  binary to decimal: Σ(bit × 2^position)

  Calculate
• 💻

  Hex Calculator

  technology

  Hexadecimal arithmetic, conversions to/from decimal, binary, and octal.

  hex to decimal: Σ(digit × 16^position)

  Calculate
• 🔢

  Base Converter

  technology

  Convert a number between any two bases from 2 to 36.

  value = Σ(digit × base^position)

  Calculate
• 🌐

  IP Subnet Calculator

  technology

  IPv4 subnet breakdown from CIDR (e.g. 192.168.1.0/24).

  hosts = 2^(32 − CIDR) − 2; network = IP AND mask

  Calculate
• 🔐

  Password Generator

  technology

  Generate strong random passwords with custom character sets.

  random = crypto.getRandomValues(buffer)

  Calculate
• 🎲

  Random Number Generator

  technology

  Generate random integers in a range, dice rolls, or coin flips.

  result = min + rand × (max − min + 1); crypto where available

  Calculate
• ⚡

  Ohm's Law Calculator

  engineering

  Solve for voltage, current, or resistance using V = I × R.

  V = I × R ⇔ I = V / R ⇔ R = V / I ⇔ P = V × I

  Calculate

  Resistor Color Code

  engineering

  Read a 4-band resistor from its color bands.

  R = (10·d1 + d2 + d3) × 10^multiplier (5-band adds a 3rd digit)

  Calculate
