uCalc

Current scientific calculators only do half the job,  they calculate the numbers whilst leaving out the units. Keylink’s calculator does both and it does it in a very easy to use intuitive way. The calculation (shown on the right) for the force on a 10kg mass at the Earth’s surface is simply calculated by using the usual keystrokes with a few extra to specify the units. For example:

 

Clicking on G for the Gravitational constant in the bottom left panel followed by the usual multiplication key.

 

Selecting the mass of the Earth from the Constants/Astronomy menu followed by the usual multiplication key again (the units are automatically included).

 

Selecting the digits one and zero from the number pad and then the units (kg) from the units panel

 

Selecting the division operator from the Operators panel on the right.

Selecting an open bracket from the Operators panel.

 

Selecting the radius of the Earth from the Constants/Astronomy menu followed by a closing bracket.

 

Clicking on the up arrow to raise the denominator to a power and then clicking on the number 2.

 

Finally the equal sign is clicked on and the/answer is calculated and displayed with the correct units!
