This is a chart to calculate the current flowing through a fuse by measuring the voltage across the fuse. A fuse has a small resistance and the current flowing through it causes a voltage drop. Measuring this voltage drop with a decent quality voltmeter can give you a good indication of the current flowing through the fuse.
The voltage drop is measured in millivolts (mV) and the fuse current is given in milliamps (mA).
1000mV = 1 volt
1000mA = 1 Amp
There is likely to be differences in the resistance of fuses between manufactures, but I'm guessing this method is likely accurate to within 10%
Unfortunately it only lists newer ATO, ATC, Maxi, mini, and Jcase fuses. Maybe there is a similar chart for glass fuses out there somewhere.
More information on this method is available on the website I found this chart at:
