Internet Speed CalculatorComputes the data a stream consumes over a period from its bitrate, and the bandwidth a number of concurrent streams needs.Netmask CalculatorDerives network address, broadcast, usable host range, mask, wildcard and subnet division for an IPv4 address and prefix.Bottleneck CalculatorCompares the CPU and GPU utilisation you measured while running your own workload, names which component is the limiter, reports the headroom left on each, and gives the best-case uplift removing that limiter could produce.Computer Power CalculatorSums the peak DC draw of every PC component, adds headroom, rounds up to a standard power-supply size floored by the GPU maker's minimum, and reports PSU load, AC wall draw at a chosen 80 PLUS efficiency and the ATX 3.x transient budget.Computing Power CalculatorSums the peak DC draw of every PC component, adds headroom, rounds up to a standard power-supply size floored by the GPU maker's minimum, and reports PSU load, AC wall draw at a chosen 80 PLUS efficiency and the ATX 3.x transient budget.Raid Array CalculatorComputes usable capacity, redundancy overhead, fault tolerance and rebuild time for a RAID array of a given level and disk count.Ppi CalculatorComputes pixel density, physical width and height, and aspect ratio from a screen resolution and diagonal measurement.Dpi CalculatorConverts between image pixel dimensions, print size in inches or centimetres and pixel density, and works out how many photos of a given file size fit on a memory card.Gifs CalculatorConverts between image pixel dimensions, print size in inches or centimetres and pixel density, and works out how many photos of a given file size fit on a memory card.Regular Expression CalculatorTests a regular expression against a piece of text with a linear-time engine that cannot hang: it simulates all match paths at once instead of backtracking, so hostile patterns like (a+)+b finish in milliseconds. Matching is leftmost-longest, which can pick a longer match than JavaScript would. Backreferences and lookaround are refused rather than faked.Bitrate CalculatorRelates video bitrate, duration and file size, solving for whichever is unknown, and reports the storage a recording consumes.File Size Video CalculatorRelates video bitrate, duration and file size, solving for whichever is unknown, and reports the storage a recording consumes.Video Recording Size CalculatorConverts a video bit rate and duration into a file size, and works out how many such recordings fit in a given card or drive capacity, how much space is left over, and how many hours of footage the capacity holds.Latex Equation Editor CalculatorConverts an ordinary calculator expression into LaTeX and LaTeX back into calculator notation, evaluates either, and verifies the conversion by comparing the two forms at sample points.Video Surveillance Storage CalculatorConverts a video bit rate and duration into a file size, and works out how many such recordings fit in a given card or drive capacity, how much space is left over, and how many hours of footage the capacity holds.
