Several sources, both experimental and theoretical, subject inclusive jet cross section measurements to large uncertainties. On the experimental side, the energy scale contributes between 10% and 30% uncertainties. On the theoretical side, choice of parton distribution function introduces a 20% variation in the prediction; freedom in renormalization scale provides another uncertainty of up to 30%. The ratio of inclusive jet cross sections reduces the uncertainty from these major sources, permitting a very precise test of next-to-leading order QCD. The preliminary results from D\O and CDF differ from simple QCD predictions in normalization and differ from each other at small values of jet $x_T$.
