What is the relative humidity if the temperature and dew point are equal?

Changes in pressure slightly modify the dew point temperature. The dew point is useful in forecasting minimum temperatures, forecasting the formation of dew and frost, and predicting fog. When the dew point equals the air temperature, the air is saturated and the relative humidity is %100.
