1.6mm
I was told that the number before the g is how many you get from 1inch of steel. ie 25.4mm / 16 = 1.58mm
The higher the g the thinner the metal.

Sorry Ewan, it's not true. Look's like you were told wrongly.
e.g. (based on SWG)
1g = 0.300" (not 1")
10g = 0.128" (not 0.1")
20g = 0.036" (not 0.05")

The higher the g the thinner the metal.
That IS true

I already bought the tubes and I doubt they are 16g. The stores I've went told me that they are 16g. Can I use 18g for the chasis and just add
additional reinforcing?

I would be very surprised if you had got hold of 18g rhs. Now is the time to purchase an accurate measuring device. Digital vernier calipers can be
had for less the £40? A worthwhile investment, then you can know what you've got rather than just guess, and you will use it constantly throughout
the build.

Stephen is right to remind me of the spirit of Locost- High-quality-plastic verniers, with a dial and accurate to .1mm, most of the time, can be had
from Axminster Power Tools for £8. or £8.50 for imperial measuring in 64ths.

they don't have everything on their web site so get them to post you a catalogue free, it's a couple of hundred pages thick, I've used them for
years and not only are the prices good but the quality is good too.

digital calipers are nice, but old analog ones are cheaper....specially when borrowed from work!
I think metal ones can be had around the price i quoted, but are slide rule not dial gauge type.

The coversions of gauge wall thickness to metric is as follows
10gauge 3mm
12gauge 2.5mm
14gauge 2mm
16gauge 1.6mm
18gauge 1.2mm
these are approximate but close enough to get you going with converting sizes.
