A Meter is about 3 feet or so anyway, very similar to a yard.
However, I tend to use generic measurement units, but my
RPGs are not focused on Tactical combat as the main focus. Besides D&D what other systems do your play-testers use?
I tend to use the following; close, short, long, extreme distance flavored to the setting. Therefore, a Sword-and-Sorcery game may be called Sword Range (close), Bow Shot (Short), Within Sight (Long), and the Horizon(Extreme).
Players really want to know, "Can I do X?" X often being can I kill these people with my weapons, because most players have been conditioned by D&D to be Murderbots.

Therefore, approximate distance is good enough to answer that basic question.
GM: They are at Long range....
Player: (Looks at sheet) Only my Sniper rifle has long-range. (Player Thinks) I can probably kill them, and they can not kill me back.
GM: They are at close range.....
Player: Good, I am better with my knife fighting so let them come close.
However, if your game leans towards Simulation, than Meters is a fine choice as NATO standard is Klicks (Kilometers) and Meters I believe. In a Simulation-focused game, then players will expect a high level of detail like equipment ranges and such; and expect them to be accurate.
GM: It is 20 Meters away.
Player: Can my Shotgun Microphone pick-up their conversation? (Checks sheet) Okay, the range is only 10 Meters for the one I have, I will need to get closer.
GM: It is 250 Meters
Player: That is well within range of my FAL rifle. The effective range is 400-800 Meters.
