Gaming & PC Calculators

12 free calculators for PC gaming: frame times, sensitivity, power supply sizing, VRAM, bitrate and more. Everything runs in your browser — no sign-up, nothing sent anywhere.

• FPS ⇄ Frame Time Calculator
  Convert frames per second to frame time in milliseconds and back, and see the frame budget you have to hit a target FPS.
• Mouse Sensitivity Converter
  Convert mouse sensitivity between games using cm/360 and DPI, so your aim carries over from one shooter to the next.
• PSU Wattage Calculator
  Estimate the power supply wattage your gaming PC needs from your GPU and CPU, with headroom for transient spikes.
• Download Time Calculator
  Work out how long a game download takes on your connection, from file size in GB and your speed in Mbps.
• Monitor PPI Calculator
  Calculate pixel density (PPI), screen width and height, and the ideal viewing distance for any monitor size and resolution.
• Streaming Bitrate Calculator
  Find the right video bitrate for your resolution and frame rate, and check whether your upload speed can carry it.
• FOV Converter
  Convert field of view between horizontal, vertical and diagonal, and across aspect ratios and games.
• Bottleneck Calculator
  Check whether your CPU or your GPU is the limit at your resolution, using your own in-game utilisation figures.
• Hz to ms Calculator
  Convert monitor refresh rate to a per-frame window in milliseconds and see how much display latency each step actually removes.
• VRAM Calculator
  Estimate how much video memory your settings need at your resolution, including texture quality and ray tracing.
• Aspect Ratio Calculator
  Scale a resolution to any aspect ratio, find the missing width or height, and check the pixel count difference.
• Game Storage Calculator
  Work out how many games fit on your SSD once formatting overhead and free-space headroom are taken into account.
