Calculators

Calculates the transpose of a matrix by swapping its rows and columns.

Calculates the amount of salt needed to raise the salinity level of a swimming pool.

Calculates the freezing point depression of a solution using the colligative properties formula. This calculator determines the change in freezing point when a nonvolatile solute is added to a solvent.

Calculates the mean and standard deviation of the sampling distribution for sample proportions (p̂).

Calculates probabilities for the number of events occurring in a fixed interval of time or space.

Recommends an appropriate ski length based on height, weight, skill level, and ski type.

Calculates the heat absorbed or released during a phase change (melting, boiling) at constant temperature (Q=mL).

Calculates the energy equivalent of mass (or vice-versa) using Einstein's famous equation.

Calculates the radius of the event horizon for a non-rotating black hole of a given mass.

Calculates stress as force applied per unit area within a material (σ = F/A).
