PURPOSE

Teletext-Tools is a Ceefax-style platform for unit conversion and simple tools.

It is built for people who want answers quickly, without modern UI clutter: GCSE students, teachers, engineers, and technicians.

Site rules are strict by design:
• NO SCROLLING
• NO OVERLAP
• PAGE NUMBERS are the main navigation

NAVIGATION

Use the PAGE box to jump instantly (3 digits).
Example: type 200 for the converters hub.

You can also tap any row to open that page.

Some pages have more than one internal screen to keep everything visible with no scrolling.
Use NEXT>> and <<PREVIOUS (or swipe left/right) to move between internal screens.

NEXT / PREVIOUS never changes the page number — it only changes the internal screen.

CONVERSIONS

Conversions use standard unit definitions where possible.
Results are formatted for readability (trim trailing zeros, avoid messy decimals).

For classroom use, some pages may favour clear GCSE-friendly conventions when that is the point of the tool.

If a result looks unexpected, check that the FROM and TO units are correct, and confirm the unit symbol.
Fast unit search: P201 (Unit Finder).

NUMBERS

Very large or very small values may be shown in scientific notation only when helpful, or on the dedicated page: P237.

RANGES:
• 210–219 core measurements
• 220–228 physics + data
• 229–237 electrical + maths
