Calculators

Analyzes forces and distances in a lever system based on the fulcrum position.

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.

Calculates the number of light bulbs needed to adequately illuminate a room based on its dimensions, desired light level, and bulb specifications.

Calculate your acceptance rate based on the number of applications submitted and the number of acceptances received.

Calculates the osmotic pressure of a solution using the van't Hoff equation. Osmotic pressure is the minimum pressure which needs to be applied to a solution to prevent the inward flow of water across a semipermeable membrane.

Calculates the number of full stacks and remaining items for a given quantity of an item in Minecraft.

Calculates electrical power using voltage, current, and resistance, based on the formulas P=VI, P=I²R, and P=V²/R.

Calculates your equivalent age if you lived on other planets in the solar system, based on their orbital periods.

Compares the unit price of two items to determine the better deal.

Calculates the energy content of natural gas in therms given its volume in CCF (hundred cubic feet).
