Calculators
Create and discover interactive calculators for various scenarios and measurements.
Battery Capacity Calculator
Calculates battery capacity (e.g., in mAh or Wh) based on voltage and charge/discharge characteristics.
Depth of Field Calculator
Calculates the range of distance in a photo that appears acceptably sharp, based on focal length, aperture, subject distance, and sensor size.
Z-test Calculator
Performs a Z-test to compare a sample mean to a known population mean or to compare two sample means when population variances are known.
T-Statistic Calculator
Calculates the t-statistic, used in hypothesis testing when the population standard deviation is unknown. This calculator helps determine if the difference between a sample mean and a population mean is statistically significant.
Fielding Percentage Calculator (Baseball)
Calculates a fielder's efficiency by dividing successful plays (putouts + assists) by total chances (putouts + assists + errors).
Capacitance Calculator
Calculates the capacitance of various capacitor configurations.
Redshift Calculator
Calculates the shift in wavelength of light due to the Doppler effect or cosmological expansion.
Hubble Law Distance Calculator
Estimates the distance to galaxies based on their redshift (recessional velocity) using Hubble's constant.
Income Tax Calculator
Calculates the income tax payable based on the user's income and a given tax rate.
Loan Amortization Calculator
Calculates the amortization schedule for a loan, showing the breakdown of each payment into principal and interest.
