General relativity involves several quantities whose overall signs are matters of convention. For some of these quantities, almost all of the sources surveyed use the same sign conventions. The variability in conventions for the metric tensor and the curvature tensor is greater. This article highlights some sign conventions that appear to be standard and describes some of the effects of changing the signs of the metric and curvature tensors. This can be used as a reference when comparing results from different sources.
