13 calculators- AI Token Cost CalculatorWhat a month of AI coding costs: input and output tokens times the price per million you enter, times the sessions you run.
- Bandwidth-Delay Product CalculatorData in flight on a link: bandwidth in Mbps times round-trip time in ms, in kilobits.
- Base64 Size CalculatorHow large a file becomes once it is Base64 encoded: every 3 bytes turn into 4 characters, padding included.
- Bits Needed CalculatorHow many bits it takes to label N distinct values — the ceiling of log base 2 of N.
- Color Depth CalculatorHow many colors a given bit depth can show — 2 raised to the number of bits per pixel.
- Compression Ratio CalculatorCompression ratio from the original and compressed size, with the space saved in percent.
- Dot Pitch CalculatorDot pitch in millimetres from pixel density: one inch is 25.4 mm, divided by the PPI.
- Download Time CalculatorHow long a file takes to download at a given speed, with bits and bytes kept apart.
- Megapixels CalculatorMegapixels from the pixel width and height of a photo or sensor — width times height, divided by one million.
- Number Base ConverterConvert a decimal whole number into binary, octal or hexadecimal — the number systems used throughout computing.
- Password Entropy CalculatorEntropy of a randomly generated password in bits — length times the base-2 logarithm of the character pool.
- Signal-to-Noise Ratio CalculatorSignal-to-noise ratio in decibels from two amplitudes, using 20 times the base-10 logarithm.
- Subnet Hosts CalculatorUsable IPv4 addresses from a CIDR prefix, including /31 links and /32 host routes.
