About Calculat.ca

Calculat.ca is an independent Canadian website that builds free, simple calculators for everyday questions.

We believe a calculator should give the answer in seconds, show how it got there, and work perfectly on a phone. Every tool on this site is written and tested by our team, and every page explains the formula behind the result so you can check it yourself.

What you will find here

• School and math tools: fractions, GPA, final grade, averages.
• Health estimates: daily calories and pregnancy due dates.
• Work and home tools: hours worked, discounts, square footage and unit conversions.
• Guides that explain the math in plain language.

Our standards

We use published formulas and official sources, review our tools regularly and correct errors quickly. Health tools are for general information only and never replace advice from a professional. The site may display advertising to stay free; advertisers have no influence on our content.
