This is how you do range math. Check it out.
There is 91.44 meters to every 100 yards. So if I wanted to do the math in my head its simple.
I take the 9 from the 91.44 as a constant.
I go 2 "200yds" x 9 = 18 move the last 0 in 100 to the end of the 18 and get 180meters
This is very close and will still get a hit on target. the difference between 90 and 91.44 is not much.
Here are some more yards to meter range math:
2 "200yds" x 9 = 18 move the last 0 in 200 to the end of 18 and get 180meters
3 "300yds" x 9 = 27 move the last 0 in 300 to the end of 27 and get 270meters
4 "400yds" x 9 = 36 move the last 0 in 400 to the end of 36 and get 360meters
5 "500yds" x 9 = 45 move the last 0 in 500 to the end of 45 and get 450meters
6 "600yds" x 9 = 54 move the last 0 in 600 to the end of 54 and get 540meters
So on it goes
going from meters to yards is the same game just a different direction.
What you do is go with the same 9 from the 91.44
I take the 2 "200meters" x 9 = 18 drop the two 00 in 200 and insert the 18 for 218yds
Now lets look at the same distances just in meters
3 "300 meters" x 9 = 27 drop the two 00 in 300 and insert the 27 for 327yds
4 "400 meters" x 9 = 36 drop the two 00 in 400 and insert the 36 for 436yds
5 "500 meters" x 9 = 45 drop the two 00 in 500 and insert the 45 for 545yds
6 "600 meters" x 9 = 54 drop the two 00 in 600 and insert the 54 for 654yds
Granted you are off by 1 or 2 yards but it gets hits anyhow
So on it goes
