"Following the loss of the Mars Climate Observer, the NASA Office of Inspector General initiated a review of the Agency's use of the metric system. By law and policy, the metric system is the preferred system of measurement within NASA. However, our review found that use of the metric system is inconsistent across the Agency. A waiver system, which was required by law and put into effect to track metric usage and encourage conversion, is no longer in use."
