Frequently asked questions
Is this calculator free?
Yes. Every calculator on CalcNepal is free, needs no sign-up and works in your browser on phones, tablets and computers.
How do I calculate a percentage?
Type the number followed by %, for example 200*15% gives 30. For more percentage problems, use the Percentage Calculator.
Why does sin(90) not give 1?
The calculator is probably in radian mode. Tap the angle button so it shows DEG, then sin(90) = 1.
Does it work offline?
Yes. After your first visit the site is cached, so the calculators keep working without internet.
