Note that many countries that use metric units tend to measure rainfall data in millimeters per hour (mm/hr). In all three Hydraflow Extensions, the rainfall data is shown as centimeters per hour (cm/hr), for example in the Intensity-Duration-Frequency (IDF) Curves or the Precipitation dialog boxes. Be sure to convert millimeters to centimeters to avoid errors.
