Calculators

This calculator helps track pregnancy milestones in rabbits by calculating key dates based on the breeding date.

This calculator determines the optimal annealing temperature for PCR based on primer sequences. The formula used is Tm = 2 * (A+T) + 4 * (G+C), where Tm is the melting temperature.

A comprehensive tool for managing sourdough starters, including ingredient ratios for maintenance, feeding schedules, flour types, hydration levels, fermentation tracking, and temperature guidance.

This calculator demonstrates the behavior of floating-point numbers in calculations and highlights potential precision issues due to the way computers store and manipulate these numbers. It allows you to input two numbers and an operation, then displays the result and the difference between the calculated result and a more precise value.

Finds the smallest and largest values in a dataset.

Calculates the change in length, area, or volume of a material due to a change in temperature.

This calculator helps you estimate how much you need to save for retirement based on your desired retirement income, current savings, and other factors.

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

Calculates the volume in cubic yards for common shapes like rectangular solids, cylinders, and spheres. Useful for estimating material quantities like concrete or gravel.

Calculates the total pressure of a gas mixture using Dalton's Law of Partial Pressures.
