Calculators

This calculator helps you convert between different concentration units, including molarity (mol/L) and percentage concentration (% w/v, % v/v, % w/w).

Calculates the percentage by mass of each element in a chemical compound.

Calculates the suggested tip amount and total bill based on the bill amount and desired tip percentage.

Calculates the inventory level at which a new order should be placed to avoid stockouts.

Estimates maximum heart rate based on age. Several formulas exist, providing different estimates.

Estimates the number of calories burned climbing stairs based on weight, time, and the number of steps climbed.

Estimates calories burned while walking, based on distance, time, and weight.

Solves kinematic equations for motion with constant acceleration (Displacement, Initial Velocity, Final Velocity, Acceleration, Time).

Calculates the change in position of an object, often using kinematic equations (SUVAT).

Calculates velocity based on displacement and time, or using kinematic equations.
