About Hydraulics Calculators

Hydraulics Calculators is a collection of fast, free calculators for the people who work with hydraulic equipment: technicians, heavy-equipment mechanics, maintenance crews, engineers, fabricators, farmers, machine builders, repair shops, DIY builders and students.

The calculators are the product. Each one runs in your browser, shows its math, and uses clearly stated standard formulas. Results are labelled as theoretical wherever real-world losses matter.

New calculators are added one at a time, and each is checked before it goes live.
