Calculators

Calculates the area of a space in square yards and estimates the material cost based on the area and price per square yard.

Calculates the area in square feet for different shapes, including rectangles, circles, and triangles.

Calculates the gallons of liquid needed to cover one square foot at a specific depth.

Calculates the saponification value of a fat or oil, which represents the amount of base (typically KOH) required to saponify 1 gram of fat. This value is crucial in soap making and lipid analysis.

Calculates the vapor pressure of an ideal solution using Raoult's Law. It can also determine the vapor pressure and mole fraction of a pure solvent in a solution.

Calculates the pH, pKa, or the ratio of acid and conjugate base concentrations using the Henderson-Hasselbalch equation. This equation is commonly used in chemistry, biology, and medicine to estimate the pH of a buffer solution.

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

Calculates the force of static or kinetic friction based on the normal force and coefficient of friction.

Performs the sum of two or more numbers.

Calculates the result of increasing a number by a specific percentage.
