 Hello! Please see the attachment. Why is this happening? I need my results in Newton or KNewton. Can you help me identify the problem here? Thank you!

This happens because you are facing an experimental formula with implicit units. Here, as per definition, f.ck must be entered in [MPa], B and H in [mm], and then the result is returned in [N]; if you do a dimensional analysis, this could work only because the "magic numbers" 100 and/or 0.12 have implicit units. To make it work in SMath, you have to divide f.ck by the expected input unit and multiply the formula for the expected output unit. ![2023-10-17 13_21_14-SMath Solver - [Worksheet1_].png](/forum/resource.ashx?a=48238&b=2) Edited by user 18 October 2023 00:30:50(UTC)
| Reason: wrong output unit, my bad |

If I multiply it by N/mm2 I get the N result because of the B and H being in mm.

Yes, sorry, obviously B and H are inputs with units too  Edited by user 18 October 2023 04:26:09(UTC)
