737 Fuel Gauge

[LOWI]

Does anyone know if the "dashed lines" on the 737 fuel gauge show or refer to a quantity or something else?

With the wing tanks full, the white line fills to the end of the last line.

Like in my car, one bar of petrol represents about 90 miles. Do the lines represent something similar?

It’s an analogue indication of tank contents as a percentage, each line indicating 10%. The picture you posted shows both tanks at approximately 62% full. It is easier to get a quick idea of contents with a glance on an analogue gauge rather than a trying to digest exact figures.

Indeed, it's supposed to imitate the look of the classic fuel gauges (both the newer LCD types and the older mechanical ones), they have similar marks.

Looking at your picture, using the old rule of thumb say 1200kg per engine per hour, you have roughly 2 hours fuel left.

Looks like for both the pound and kilo indicators there are 10 lines, so I don't think it refers to a specific weight, just a easy way to judge how much you have (as a percentage of full).
