How to determine the actual distance at the driving range?

If I practice golf at 2nd floor of OCC driving range and the ball reach 100m mark, what is that equivalent distance at ground level? 90m?

Use a Rangefinder with slope/elevation features ...

TS.... u do realise that the compression of range ball is different from actual golf ball

what u hit at driving range may not be the same as on the golf course... even at level elevation

please factor that in....

At the driving range, just practise ball strike. For distance, I think better to judge on course or maybe even simulator might help with that.

Read once range ball is  of different quality.e wise man told me  Practice crafting instead of going for distance.

OCC balls won't fly far one,practice ball striking and short game pitching better..Marina Bay n punggol range have better balls maybe 5-8% differential IMHO..it also varies on what kind of bullets(balls) u used when on battlefield ..

It also depends on how well you can compress the range balls. Some ppl will complain that they can't hit their 4,5,6 irons pass 160m.

the purpose of range practice shouldn't be focused on distances, but to build muscle memory through practice. Developing consistency, accuracy and tempo. Go to the range with a specific intention. Hitting hundreds of balls with the wrong swing may just reinforce bad habits that will be hard to get rid of in future.

Observe better golfers on the range and watch what they do. Pick out specific targets and treat it like you're actually playing a hole. like a par 5 so you can hit 3 shots. i.e Wood->iron->wedge.

To practice consistency and tempo, i'd line up just 3-5 balls and hit one after another with a smooth swing. dun care how far the ball goes. most important is that they all go in the same direction and trajectory. Never forcing any shots.

To practice accuracy, I'd hit driver... if drive goes left.. i'd pick out a target on the right. depending on which iron I wanna work on.. eg, 7 iron to a right pin at 140-150m. then let's say I miss right.. i'd pitch to a target on the left.  

Hope it helps.

I rarely use the range for distances. As mentioned, it's difficult to get a good assessment of distance. What I typically do is to accept that with range balls, I'm losing about 10% of distance. You can figure out the maths backwards from there.

As for tee'ing off from a high floor, I think it's even more difficult to assess distance here. In such situations, I rarely ever use my shots as a calculator for distance. From high(er) floors, I'm more interested in making sure I can hit the ball straight. And, that alone, takes up more time than trying to figure out how far I hit the ball.

From my recent experience, hit 6 iron on 2nd floor and it landed on 150m target... actual distance i hit on green is 160m...  so for me it is 10m shorter for range ball.

There's a way and i believe the only. 
Used your own branded balls be it Slazanger, Dunlop, Srixon, Volvik, titleist etc. 
Can be a used ball.
But again, one must be able to strike it clear/well inorder to justify the more accurate distances.
Otherwise just work on to achieve a proper/correct swing.

The difference could be more than 10m for some range balls depending which range as range ball is of very low compression and don't forget u hit from 2nd level. Your distance using range ball might be 140m if you hit from ground level ... Some range balls are of 1-piece construction only ...
