Universal Soil Loss
Universal soil loss, abbreviated as USLE, predicts the potential long-term average annual soil loss per unit area.

| Symbol | English | Metric |
| \(\large{ A }\) = estimated annual soil loss | \(\large{tons-acre-yr}\) | \(\large{tonnes-hectare-yr}\) |
| \(\large{ C }\) = crop/vegitation and management factor | \(\large{dimensionless}\) | |
| \(\large{ R }\) = R factor - rainfall and runoff by geographic location (the summed erosive potential of all rainfall events in a year) | \(\large{dimensionless}\) | |
| \(\large{ LS }\) = slope length-gradient factor | \(\large{dimensionless}\) | |
| \(\large{ P }\) = support practice factor (reflects the effects of particles that will reduce the amount and rate of the water runoff and thus reduce the amount of erosion) | \(\large{dimensionless}\) | |
| \(\large{ K }\) = soil erodibility factor (units of soil loss per unit of soil erosivity) | \(\large{dimensionless}\) | |
