Calculators

Determines the grade needed on a final exam/assignment to achieve a desired overall course grade.

Calculates the component values (e.g., in L-networks) needed to match impedances for maximum power transfer.

Finds the Z-score corresponding to a given cumulative probability (percentile) on a normal distribution.

Calculates appropriate training paces for different types of runs based on a recent race time and distance.

Estimates the total surface area of a human body using various formulas. Body surface area (BSA) is the measured or calculated surface of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal body fat. BSA is an important factor in many physiological and clinical situations.

Converts a decimal inch measurement into its equivalent fractional representation (inches and fractions of an inch).

This calculator converts pressure between torr and atmospheres (atm).

Calculates the volume or number of moles of a gas at Standard Temperature and Pressure (STP). STP is defined as 0°C (273.15 K) and 1 atm pressure. This calculator uses the ideal gas law to perform these calculations.

This calculator converts volume measurements (in cups) to weight measurements (in pounds) for various ingredients commonly used in cooking and baking. It supports multiple ingredient options to provide precise measurement conversions.

Calculates the change in angular position of a rotating object.
