27 1/4??? Do you mean 27 x 1 1/4?
And what do you mean by "equivalent"? You can't put a 700 tire on a 27" rim. Do you mean, what 700 rim/tire combination will give a similar ride to a 27" rim/tire combination? Then you probably just want a similar tire width. To convert from inches to millimeters, multiply by 25.4, so 1 1/4" -> 32 mm.

Give a man a fish...... 
The number that you'll find helpful is that 1"=25.4mm
So.... 25.4x1.25= 31.75. a 32mm tire is closest to 1.25"
Also second/third that 700 and 27 are incompatible rim/tire sizes. a 700c rim will have a 622 bead diameter.
