PSU wattage estimation, RAID capacity, PPI, download time and video bitrate. The bitrate tool shows how much less H.265 or AV1 needs than H.264 for the same quality.
Download Time CalculatorCalculate how long a download takes from file size and connection speed (Mbps/Gbps), with bits-vs-bytes handled correctly and common speed presets.Video Bitrate CalculatorConvert video bitrate and duration to file size, or a target file size to the required bitrate — with YouTube upload bitrate reference values.PSU Wattage CalculatorEstimate your PC build’s power draw by component tier (CPU, GPU, drives, fans) and get a recommended PSU size with healthy headroom for GPU spikes.RAID CalculatorCalculate usable capacity, storage efficiency and fault tolerance for RAID 0, 1, 5, 6 and 10 from your drive count and size.PPI CalculatorCalculate a display’s pixels per inch, dot pitch and megapixels from its resolution and diagonal size, with common monitor comparisons.
