But why not make it even simpler? Take the meter apart, and locate
the series resistor. Replace it with a resistor of half the value.
Then you'll have a 0-5V meter, and no power-draining op amp circuit
will be required.

I started to post an answer like that, until I realized that he
didn't specify what kind of meter.

I'd even go further, to point out that while analog meters have
all kinds of scales, they may not even have a resistor built in.
They might just be a current meter and expect an external resistor
in order to read whatever is on the scale. This the more so
if it's just the movement, but obviously not the case if it's an
actual "voltmeter" with the movement in a box etc.

If it's just the meter movement, and does not actually have the
resistor inside, then one has to calculate the resistor value
using ohms law.
