All of our products support the English and SI unit systems. When you change an input or output unit, the inputs or output pages dynamically changes to reflect that change.
When ACI 318 and IBC concrete design codes are selected, both English and SI units are available for input and output. When other concrete design codes are selected, only the SI units are available for input and output.
Note on Rounding: Due to rounding of numbers, the sum or difference of two dimensions may not be exactly equal to the third dimension as noted on some dialog boxes. For e.g. on a pile location plan, the sum of the pile ring radius and the edge distance may not exactly equal half the out-to-out octagonal footing size.
