Frequently Asked Questions

What unit types does the Unit Converter support?
The unit converter handles length, weight, temperature, volume, area, and speed — covering the most common metric-to-imperial and imperial-to-metric conversions needed in everyday life.

Can I download the QR code I generate?
Yes. Download a single QR code as PNG, scalable SVG or PDF. Batch CSV jobs can be packaged as ZIP files, SVG sets, mixed formats, PDF booklets, label sheets, posters or business-card layouts.
-
Does the Time Zone Converter adjust for daylight saving time?
Yes — the Time Zone Converter accounts for daylight saving time rules for all supported regions, so the converted times are accurate year-round.

Can the Date Difference Calculator count business days?
Yes. Business-day mode counts eligible weekdays between two dates and excludes weekends. Choose the US or EU holiday calendar, import up to 40 custom holidays, or skip weekends only. You can also add business days to a start date and plan holiday-aware project phases. The calculator also supports exact date spans, work-planning buffers, and recurring schedules.
