An inch is defined as exactly 2.54 cm.  How many cm in 964.307 inches?
MUST BE TO THE EXACT SIG FIGS
*Answer cannot be in scientific notation

My attempt:
964.307 inches x 2.54cm/in = 2450 cm

However 2450 is not correct. Maybe my sig figs are wrong, but I thought when you multiply the one with the fewest sig figs are obtained... Does anyone know what my error is?

Since one inch is exactly 2.54 cm, this number has an infinite amount of sig figs.

You are correct that when you multiply the one with the fewest sig fis is used.  However, the key phrase in this problem is "defined as exactly".  That means, 1 inch = 2.54 cm, is not an estimate, but an exact property.  Because of that, it is considered to have infinite sig figs, so your limiting value is the 964.307

I do believe, if I and my knowledge are not wrong, to write it in the significant figures, you could write it this way: 2450.00 cm. That comes to 6 sig. figs. and thats how many are in question value: 964.307 in.
