@forbesy71 Create a custom format like this [ss].000





Thanks for the reply, i have done that but i'm after the formula or steps to do it as below




@forbesy71 Sorry, but I don't understand what you mean by "I'm after the formula or steps to do it".

Sorry for the confusion,

What I want is, if i enter 1:30.009 into cell A1, i want it to display in cell C1 as 90.009 automatically.

Hope this explaination helps.

@forbesy71 The simplest "formula" in C1 would be =A1 and than set the custom format for C1 to [ss].000


Alternatively, you could use the TEXT function that allows you to type the desired format into the formula between quotation marks. Using a double hyphen (i.e. two minus signs) in front forces it to become a numeric value.

= --TEXT(A1,"[ss].000")

Thank you Riny, that's got it, I didn't have the brackets around the ss in the formating.
Muchly appreciated
