Hi all, some problem which unit calculation
K:8.87 α:1 β:0.43 γ:0 b:200*'мм
Kα:K*(α+(β*{α^2}/{b^2})+(γ*{α^4}/{b^4}))^0.5=#
result: Unit does not match((((

The error seems correct. Just make a dimensional analysis on α+(β*{α^2}/{b^2})+(γ*{α^4}/{b^4}) You sum something dimensionless with 1/мм^2 and 1/мм^4 Edited by user 01 February 2015 15:41:03(UTC)

You sum something dimensionless with 1/мм^2 and 1/мм^4 I`m not convert unit of measure, math operation only value. mm^4 you real?? what a dimension, square? cube or astral?

Maybe the attached picture helps a little bit more to understand the issue... As stated previously, you can't sum apples and oranges; therefore the error message seems consistent... Edited by user 03 February 2015 11:12:31(UTC)

Thanks for sharing the original formula, this makes more sense; seems you have missed or merged a parameter (alpha) with a variable (a) Best regards, Davide Edited by user 04 February 2015 01:40:15(UTC)

Seems strange, because in this way the formula has both mathematical sense (alpha*x^0+beta*x^2+gamma*x^4) and physical sense (homogenous units involved in the calculation)... there is some literature about this formula? (where it is used? has an author?) Edited by user 05 February 2015 01:30:12(UTC)
