Physics Calculator
Physics: it evaluates the numeric expression you enter — after you substitute values into a physics formula — using standard arithmetic and scientific functions; it does not track or enforce units. Worked through below with real figures, and the calculator repeats the working on your own inputs — free, on-device, instant.
Give Physics Calculator your expression and it returns the numeric result straight away. Built to evaluate a physics-style numeric expression, it runs entirely on your device.
About this calculator
It matters when grades, percentages or averages decide a next step and hand arithmetic is error-prone. The governing relationship: It evaluates the numeric expression you enter — after you substitute values into a physics formula — using standard arithmetic and scientific functions; it does not track or enforce units. See it on real numbers: Using v = u + at, an object starting at 5 m/s accelerating at 2 m/s² for 3 s reaches 5 + 2×3 = 11 m/s . The calculator above applies the same steps to whatever you enter — computed locally, nothing sent anywhere.
How to use
- Type a numeric expression, such as 0.5*2*3^2.
- Use + − × ÷, powers (^), and parentheses.
- Press Calculate to evaluate the expression.
- Read the evaluated result.

Technical notes
Physics Calculator evaluates the numeric expression you enter — after you substitute values into a physics formula — using standard arithmetic and scientific functions; it does not track or enforce units.
Results assume ideal conditions and consistent units, so convert your inputs to the units shown before calculating.
All arithmetic runs in your browser using double-precision floating point, so extreme inputs may show tiny rounding differences.
FAQ
What can this calculator do?
It evaluates numeric expressions you type, which is handy for plugging numbers into physics formulas like ½mv².
Does it know physics formulas or units?
No. It is an expression evaluator, not a symbolic solver, so you supply the numbers and it computes the result.
Is it safe?
Yes. Expressions are parsed by a math evaluator, not executed as code, so only arithmetic is performed.
Does the Physics Calculator send my data to a server?
No. The Physics Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
Using v = u + at, an object starting at 5 m/s accelerating at 2 m/s² for 3 s reaches 5 + 2×3 = 11 m/s.
