The overall length of an M16A4
I didn't even know what a M16A4 is. Some US unit, right?
Yes, with the official M16A4 unit being defined as 1/100th the length between the goal lines of an American Football field.
approximately 1.06 × 10⁻⁷ nanolightyears
Take a really long rope and put one end on either pole of the Earth, and the other end on the equator. Use the shortest path, and make sure the rope is tight. No squiggles allowed! Chop that rope into exactly 10 000 000 equal parts. One of them is as long as a meter. Now you just need to find the right one.
Edit: more zeros.
Half the width of a car.
USA moment.

You mean the the square root of the surface of Saarland divided by 2,569,690?

Okay, so, right, okay. Um. In German schools (and probably some other countries...?), many many years ago (possibly still today? or maybe it's all digital now? what am I saying, this is German schools), the blackboard in every classroom was a large, green, rectangular middle part and two square "wings", one on each side (as wings are wont to be...). They can swing in and out, providing extra room for writing on the outer side of the wings. Also for extracurricular shenanigans such as writing "[name] + [name] = SEX" in the middle, swinging the wings closed to hide the writing and then breaking out into hysterics when the teacher opens the blackboard to reveal your incredibly highbrow joke.
This type of blackboard is quintessential to my recollections about and concept of school.
Why am I going into such unnecessary detail about this? I have ADHD and possibly autism, I need you to understand what I'm saying and I can't find any sources of this existing in the English speaking world and I can't find an English word for those "wings" either. I can barely find a German one ("Tafelflügel"? I don't think it's ever come up before in my life).
So here's a picture:
The width/height of the "wings" and the height of the middle part, that's a metre. Thank you for coming to my TED talk.
Does the metallic edge count as part of the meter too or just the green surface? What if it's so hot the wings expand?
Just the green. This is special German engineering high-tech space material whose name I absolutely do know but am not at liberty to divulge and that doesn't expand (i.e. I've never experienced a blackboard being warmer than slightly cool to the touch).
Try to piss as far as you can. Now you know how long a meter is.
But how do we measure the lenght? Do we have to find a way which includes the last drop? And what if I don't have a penis?
"The length of the path travelled by light in vacuum during a time interval of 1/299792458 of a second, where the second is defined by a hyperfine transition frequency of caesium."
This is the actual definition, but it's also pretty weird.
From the tip of your right thumb to your left nipple. Too sensible?
As long as a clap
A bit more than 90 centimetres, a bit less than 110. Somewhere in that ballpark.
Just about half as twice as much.
