Mercifully, g=9.8 everywhere on Earth’s surface, so we use weight interchangeably with mass, but yes, we should weigh ourselves in Newton: “I need to lose 10kg, so I can reach my ideal weigh of 700N” :P
We already have a permanently inhabited base outside Earth (ISS) with effectively zero gravity and there might be one on the Moon or Mars in 100 years. We should pass treaties to only use metric in space – a probe has been lost to unit confusion already.
Everything experiences different gravity (and “apparent gravity”) in space. We should pass a treaty of using metric only there, if only to avoid losing more spacecraft.

Big nope. It depends not only on height, but also on density of stuff under ground.

This is dated 2007. Apparently NASA is already using metric:
NASA Finally Goes Metric
I know, it has always used metric but the SW was by Lockheed Martin. Still, we need to convince potential extraterrestrial civilians.
On ISS it’s ≈.89g, but agreed
I said “effectively zero gravity” for a reason – the term is “zero gravity” but I know it’s a misnomer.
I’d say it’s more of a “small yes” than a “big nope.”
While gravity does vary, it goes from about 9.76 to about 9.83.
All of which does, in fact, round to 9.8
On ISS it’s 8.722, but it’s constantly falling.
