Due to the expansion of space how long will 1m of space be next year?

Due to the expansion of space how long will 1m of space be next year?
I think that depends on where in space it's located.
Space cannot be measured, it has no length.
Things have positions in space. Those can be differentiated to give up measure/length.
So your good old meter stick will still be that in some million year.
Maybe some value considered constant (like the speed of light) are not so constant over long period of time (experiment are running), making your meter stick no more standard. But it is unlikely.
Base unit definitions: Meter
The meter is the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second.
Perhaps the question is intended to ask how much will the space expand maybe? My understanding is that is it really really small. 0.7 km per million light years per second.
My question was intended to get a feel for the order of magnitude of the the expansion of space.
I was under the assumption that space itself does actually expand and can even cause distant objects to exceed the speed of light relative to one another.
You can look up what physicists state about:
How old is the universe?
What size was it when it started?
What size was it after 1 picosecond, nanosecond, second, year, 100 thousand years, million years etc
There is a period called inflation where expansion was extraordinarily rapid. (don't ask me I am just a bystander)
How large is the visible universe now?

According to Jilans answer and a few quick calculations results in a meter of space expanding to 1.00000000000233m over one year.
Thanks!
a change of 2.33E12, 2.33 pico meters in one year
That's about the wavelength of some gamma rays, 1000 protons lined up or 1/30th of a helium atom.
Does that even make sense?
For one american billion years 2.33E12 x 1E9 = 2.33E3 = 2.33 mm
Ten american billion years 2.33E12 x 1E12 = 2.33E3 = 23.3 mm

You know how compound interest works? We could try applying the same principle and see what that gives instead.
Good one... Chuckle chuckle,
Continuous compounding gives a 23.6 mm increase after 10 billion.
Are you compounding each second or each year?
Continuous Compound Interest Formula
The limit of the interval goes to zero. But you know that. snort.
It doesn't seem very much does it?
Jilan, you stated: 0.7 km per million light years per second.
That is 2.33E9 m/m per second
Componded continuously for one year 1 meter goes to 1.076 meter. A 76 mm growth per year.
Hmmmm. snort for this.and snort for all 2.33E12 calculation.
Your turn
I think your calculation in post #12 looked right.
Have you got a cold?
Question becomes: How or where did you get "0.7 km per million light years per second"?
Oh I see, my megaparsec conversion got screwed up! very sorry....
Let's try again..... How does 23 km/s/million light years sound?
Fool me once, shame on you. Fool me twice shame on me.
I'll wait for the one meter for one year answer from you. This arithmetic is not enriching my life.
I agree, it's best to save the brain cells for old age, we might need them but I just can't resist....
I'm coming up with 7.7 x 10^13 m/year/m
Oh dear, it's even smaller! I don't think we humans are designed to work with such small numbers. lol.
Small numbers? Go for 16 point font. If not try 24. Yuk yuk yuk.
