Frequently Asked Questions

How accurate is the rainfall tracker for garden watering calculations?

The tracker accurately calculates cumulative totals based on your input data. For garden watering, accuracy depends on the precision of your rainfall measurements. Use a standard rain gauge for best results and record measurements at the same time each day. The tool converts between units automatically and maintains running totals for your selected time periods.

Can I track rainfall for multiple locations or gardens?

Currently, this tool tracks rainfall for one location per session. For multiple locations, you can use the tool separately for each area and download the CSV data to combine results in a spreadsheet. Each tracking session maintains its own cumulative totals and statistics for the specified time period.

What's the difference between tracking periods and how do I choose?

Weekly tracking is ideal for short-term garden management, monthly for seasonal planning, and yearly for long-term climate patterns. Custom date ranges work well for specific growing seasons or weather events. The tool calculates cumulative totals and averages based on your selected period, helping you understand rainfall patterns relevant to your needs.

How do I convert between inches, millimeters, and centimeters?

The tool automatically handles unit conversions - simply select your preferred unit and enter measurements accordingly. One inch equals 25.4 millimeters or 2.54 centimeters. If you have mixed data sources, pick one unit and convert manually before entering, or use the tool multiple times with different units and combine the results.

Can I export my rainfall data and what format does it use?

Yes, you can download your rainfall tracking data as a CSV file that includes dates, amounts, units, and cumulative totals. This format works with Excel, Google Sheets, and other spreadsheet programs for further analysis. The export includes all daily entries plus summary statistics for your tracking period.
