It absolutely is different. It may not seem so to a non baker, but regular cooking has a lot more leeway. Baking consistently requires a much finer degree of control over the variables. The difference between "a pinch of baking powder" vs "5 grams of baking powder" is entirely different. In the first case, you're left wondering why pancakes came out good last time and why are they inedible this time.
I'm no great cook or baker, but I've learned through trial and lots of error how to bake bread and a few other things. Get a scale and always convert to grams.
