Units of measurement

﻿
💡
CalcTree allows you to create calculations that are aware of units of measurement. To learn more about the benefits of unit-aware calculations, read this article. 
﻿
Here, we explain how to use units in inputs and formulae in CalcTree. 
﻿
Units in inputsYou can enter your desired unit alongside numbers in the input fields in CalcTree. For example, if you want to enter a quantity of 1 meter in an input field, you can type 1 m, like this:

:1.00 m​

Using units in math formulas﻿
Mathematical formulas are simple calculation items on CalcTree. When composing formulas, you can use units of measurement to indicate quantities. For example, you can add two length quantities of one meter and one foot:
﻿
﻿
﻿
Units are carried over references If you reference another parameter in a formula, units of that parameter will be considered in the calculations. For example, units of A and B are carried over into the formula in D: 
﻿﻿A
:1.00 m​
﻿
﻿﻿B
:1.00 ft​
﻿
﻿
﻿
﻿
Unit conversionsUnits will be converted automatically inside a formula, for example, when adding and subtracting compatible quantities. 
If you want to convert into a desired unit explicitly, you can use the to keyword in the formula:
﻿
﻿
﻿
Available unitsCalcTree uses Math.js under the hood to handle units in Formulas. You can get the available units in formulas here on Math.js documents. 
﻿
What about units in Python?🐍  In addition to math formulas, you can use units inside Python code on CalcTree. Learn more here
