Convert any monthly USD budget into concrete engineering output across 25 popular AI coding models.

Calculate the bandwidth-delay product (BDP) of a network link from its bandwidth in Mbit/s and round-trip latency in ms — the data volume kept in flight and the ideal TCP window size.

Calculate the Base64-encoded size (ceil(n / 3) × 4 bytes) produced when you encode a given number of input bytes, including padding.

Calculate the minimum number of bits needed to represent N distinct values (bits = ⌈log₂N⌉) from how many values you have.

Calculate how many distinct colors a given color depth can represent (colors = 2^bits), from 8-bit to 24-bit true color and beyond.

Calculate the data compression ratio (original size ÷ compressed size) and the space savings percentage from an original and a compressed file size.

Calculate a display's dot pitch in millimetres from its pixel density (dot pitch = 25.4 / PPI) to see how finely a monitor or screen resolves detail.

Estimate how long a file takes to download at your connection speed, with the bits-vs-bytes conversion handled for you and the time shown in minutes and seconds.

Calculate the megapixels of an image sensor or photo from its pixel width and height (MP = width × height / 1,000,000).

Convert a decimal (base-10) whole number into binary, octal, and hexadecimal — the number systems used throughout computing.

Calculate password entropy in bits (E = L × log₂R) from your password length and character pool size, and see the strength band it lands in.

Calculate the signal-to-noise ratio in decibels (SNR = 20·log10(signal/noise)) from a signal and a noise amplitude in volts.
