Gaming Cost Per Hour Calculator

Estimate the cost per hour of gaming based on your hardware purchase price, electricity use, power cost, expected lifespan, and average weekly play time. This helps you understand the hourly cost of owning and running a gaming setup.

ADS Sensitivity Calculator

Estimate ad sensitivity score based on average daily spend, click-through rate, conversion rate, audience overlap, and industry risk level. Higher scores indicate campaigns that may be more sensitive to performance fluctuations and targeting changes.

DPI Ratio Calculator

Calculate the DPI ratio between a source image and a target output size to determine whether an image will be upscaled or downscaled for print or display. Enter the source pixel dimensions and the intended output dimensions in inches to get the effective DPI ratio.

Keyboard Polling Interval Calculator

Calculate keyboard polling interval, polling rate, and estimated input latency behavior based on USB polling rate, debounce delay, scan interval, and processing overhead. This helps estimate how often the keyboard reports input and the average time before a keypress is sent to the computer.

Input Latency Calculator

Estimate total input latency from device polling, display refresh, display processing, and system overhead. Useful for approximating the delay between a user action and the visible on-screen response.

Mouse Polling Rate Calculator

Estimate the effective input timing characteristics of a mouse based on its polling rate, sensor latency, system overhead, and USB stability factor. This calculator helps compare how often the mouse reports movement to the PC and the resulting average end-to-end reporting delay.

CM per 360 Calculator

Calculate how many centimeters of mouse movement are needed to complete a full 360-degree turn in-game based on mouse DPI, in-game sensitivity, and game yaw.

Mouse DPI Calculator

Calculate effective DPI (eDPI) and translated DPI based on your mouse DPI, in-game sensitivity, Windows pointer speed, and optional target sensitivity ratio for matching another game or setup.

eDPI Calculator

Calculate effective DPI (eDPI) by multiplying your mouse DPI by your in-game sensitivity. Use it to compare sensitivity settings across games and aim setups.

PC Heat Output BTU Calculator

Estimate the heat output of a PC in BTU per hour based on average system power draw, PSU efficiency, daily runtime, and room ventilation factor. Electrical power consumed by a computer ultimately becomes heat, and this calculator converts that load into BTU/hr and daily BTU.

Thermal Resistance Calculator

Calculate thermal resistance (R-value) for a material layer using thickness, thermal conductivity, surface area, and number of identical layers. This calculator returns the total thermal resistance for heat flow through the specified assembly.

GPU Delta T Calculator

Estimate GPU delta T, the temperature rise of the GPU core above ambient air temperature, using GPU power draw, cooler thermal resistance, fan/case airflow effectiveness, and workload intensity.

CPU Delta T Calculator

Calculate CPU delta T, the temperature rise of the CPU above ambient air, using CPU package temperature and room ambient temperature. Optional cooler efficiency and case airflow factors adjust the effective delta T to reflect real-world cooling conditions.

Fan RPM Ratio Calculator

Calculate the resulting fan speed ratio and driven fan RPM from pulley diameters and driver motor speed. This helps estimate how changing driver or driven pulley size affects fan rotational speed in belt-driven systems.

CIDR Address Count Calculator

Calculate the total number of IPv4 addresses and estimate usable host addresses for a given CIDR prefix length. The calculator also accounts for common network types where usable hosts differ, such as standard subnets, point-to-point links, and single-host routes.

Fan CFM Calculator

Estimate the required fan airflow in CFM based on room dimensions, desired air changes per hour, and system factors such as room usage and duct efficiency.

PC Fan Airflow Calculator

Estimate the total airflow delivered by PC case fans based on fan size, quantity, speed, and mounting restrictions. This calculator provides an approximate combined airflow in CFM for planning case cooling and ventilation.

Fan Speed Percentage Calculator

Calculate fan speed as a percentage based on the current fan RPM and the maximum fan RPM. Optionally adjust for a minimum stable fan speed and PWM duty cycle to estimate effective operating percentage.

PC Airflow Calculator

Estimate the recommended total case airflow needed for a PC build based on system power draw, cooling style, case size, component density, and ambient room temperature. The result helps size intake and exhaust fan capacity in CFM for balanced cooling.

Water Cooling Flow Rate Calculator

Estimate the required water cooling flow rate based on heat load, allowable temperature rise, water-glycol mixture, and system safety factor. Uses the heat transfer relationship Q = m × Cp × ΔT and converts the result to liters per minute.
