be worth to do?

Hello, red—and welcome to English Forums.

No. And I am afraid I do not understand your sentence. What does 'measuring hours to realize' mean?

Sorry. It's only the last part of the sentence. What I want to say is like this: Though the larger test dose can reduce the error of Equivalent dose, it is not worth to spend twice measuring hours to realize it.

So, what about "Though the larger test dose can reduce the error of Equivalent dose, it is not worth spending twice measuring hours to realize it."

I still ask what this means: 'measuring hours to realize.'

"spend twice measuring hours to realize it" Here I want to say: If you want a better result, you need to spend twice time on the measurement. It is not worth.
Sorry, I don't know if I can rephrase it very well in this way to make you understand.
So, what's your suggestion about this sentence?
And, please just tell me how to use "be worth to do" or "be worth doing"

red12345174"spend twice measuring hours to realize it" Here I want to say: If you want a better result, you need to spend twice time on the measurement. It is not worth.

Then:

It is not worth spending twice the time on measuring it.

Got it!
Thank you very much!!
