GUTCalc Physics Unit Converter vs CalcPad-A Physical Calculator Usage & Stats
GUTCalc is a calculator that understands units. Enter a free-form expression consisting of arithmetic, SI and non-SI units, physical constants (like Planck's constant h or the speed of light c), and functions (like exp, arctan, and cosh) and GUTCalc will work out the answer including any necessary conversions. Natural units are fully supported, and are great for calculations in particle physics and quantum field theory. SI mode is perfect for quick and easy calculations of everyday quantities.
FEATURES:
* Choose from SI and three types of Natural unit modes. In Natural unit mode, various physical constants (such as hbar, c, kb, and eps0) are set to 1. GUTCalc automatically inserts factors of these constants to perform conversions and calculations in Natural units.
* Gaussian CGS (dynes, ergs, esus, and statvolts) and Planck (quantum gravity) units are also supported.
* Multiplication is implied: no need to insert *s everywhere.
* Custom-designed keyboards for quick and easy input of common units, constants, and functions---or switch to the built-in keyboard for free-form input.
* Calculations can extend over many orders of magnitude without overflow. Need to calculate exp(10000)? No problem. (Available on iOS 11+ and 64-bit devices running iOS 10)
* Avoid algebraic errors thanks to GUTCalc's unit checking: inconsistent calculations are flagged in red with an explanatory message.
* Share your results via email or save them in a note using the share feature.
* Physical constants are updated to the latest values recommended by the Particle Data Group 2020 review, CODATA 2018, and the 2019 redefinition of SI base units.
* Suggestions for features and additional constants are welcome.
UPGRADE TO PRO FOR EXTRA FEATURES:
* Create and manage multiple notebooks to keep your calculations organized
* Sync notebooks with iCloud across multiple devices, including the macOS version of GUTCalc
* Share notebooks with collaborators
* Support the development of more pro features in the future

CalcPad is not just another calculator app among the many calculator apps. Why?
If you are using a mobile calculator app. You will find that it calculates differently from a physical calculator. Since the calculator app uses a process known as PEMDAS or BODMAS for its calculations, while a physical calculator uses a step-by-step calculation. For example 5+5/5, on the physical calculator, you will get the answer equal to 2. But if you do it on the calculator app, the answer will be equal to 6. Because the calculator app will use the principle of PEMDAS/BODMAS. It is calculated using parentheses, division, multiplication, addition, and subtraction, but a physical calculator does it step by step. That's why you will get different results.
Calculator users who want to perform sequential calculations will not be able to use most calculator apps. CalPad was created to fix this problem.
Basic features
- Calculated in sequential order, not using PEMDAS or BODMAS.
- Works on both iPhone and iPad.
- Display in both portrait and landscape on all devices.
- Large NumPad buttons on every screen and do not change the position of the button for easy muscle memory use.
- Support basic scientific calculations.
- And most importantly, it's FREE, NO ADS! (but you can tip us)
