Question 5

What is UNITS by SKALDA?

Accepted Answer

UNITS is a universal unit conversion suite with two main experiences: Smart Tab for quick single conversions and Bulk Converter for spreadsheet-like multi-column conversions. It also includes many free calculators (finance, health, geometry, DIY and more).

Question 6

What does the Bulk Converter do?

Accepted Answer

Bulk Converter lets you paste rows of values, pick a row driver (source unit), and instantly compute results across any number of unit columns. You can add/remove columns, change precision per column, and auto-save snapshots locally if Auto‑Save is enabled.

Question 7

What does Smart Tab do?

Accepted Answer

Smart Tab provides fast, single‑row conversions with tabbed categories and pinned units. You can reorder tabs, pin favorites, and your choices are stored locally (debounced) for a smoother experience.

Question 8

Do calculators auto‑save my inputs?

Accepted Answer

Yes, if the global Auto‑Save setting is on. Each calculator stores only the fields you enter in your browser so you can pick up where you left off. Disable Auto‑Save in Settings to stop saving new data.

Question 9

Where do currency rates come from?

Accepted Answer

Currency conversions use live rates from ExchangeRate‑API. Rates are cached locally for up to 1 hour to improve performance and reduce network calls.

Question 10

Does UNITS work offline?

Accepted Answer

Most conversions run fully in your browser once the page is loaded. Currency rates require internet access for fresh data, but a recent cached rate may be used if available.

Question 11

What data does UNITS store on my device?

Accepted Answer

Smart Tab stores preferences (tabs, pins, active tab). Bulk Converter can auto‑save a lightweight snapshot (visible units, column order, precision, recent table state). Calculators can auto‑save your last inputs. Currency rates and page titles may be cached. All of this stays on your device.

Question 12

How do I clear saved data?

Accepted Answer

Turn off Auto‑Save in Settings to stop new saves, and use your browser’s site data controls to clear local storage for the site. Clearing site data resets saved preferences and snapshots. See our Cookie Policy for details.

Question 13

What is FLINT?

Accepted Answer

FLINT is SKALDA’s free, browser‑based file converter that runs locally - no uploads.

Question 14

Are my files uploaded?

Accepted Answer

No. No uploads, no servers involved - conversions run entirely in your browser (client‑side only).

Question 15

Are there file limits?

Accepted Answer

No imposed file limits. There are no quotas or size caps by the app. Practical limits depend on your browser and device (memory/CPU).

Question 16

Which formats are supported?

Question 17
