Flashtool.org — Conversion Tools Only
This page is only for unit converters. It gives a list of 20 popular tools and 100 deeper conversion links. Each line has a short label and a URL. You can turn them into real pages or just use them as ideas.
Why unit converters help users
Many people need quick conversions in daily life. They do not want long text. They just want to type a number and see the answer. These tools can help when:
- Someone is cooking and needs to change cups to ml or tsp to ml.
- A student is doing homework with meters, centimeters and inches.
- A traveler wants to switch miles to km or gallons to liters.
- A shopper wants to compare weights like lbs, kg and ounces.
How to use these links
- Use the top 20 for your main home page grid or sidebar block.
- Use the full 100 list for a “All converters” page or XML sitemap.
- Copy the list as plain text or download the CSV for planning.
- Turn each URL into a real tool on your server or app.
- Mark live tools with a small “Live” label in your own system.
Suggested grouping on your site
You can split these converters into simple sections for users:
- Weight and mass: lbs, kg, oz, grams, tonne, stone, tons.
- Length and distance: mm, cm, meters, km, inches, feet, yards, miles.
- Kitchen and volume: ml, liters, cups, pints, quarts, gallons, tsp, tbsp.
- Volume shapes: cubic feet, cubic inches, cubic yards.
- “Any to any” tools: unit converter, online converter, conversion tool.
On the page, each group can have a short note like “Best for cooking” or “Useful for travel”. This makes it easy for users to pick the right tool.
Small page pattern
Each converter page can follow a very simple pattern:
- H1 title: “lbs to oz converter”, “cm to inch converter”, etc.
- One input block: from value, from unit, to unit, and a convert button.
- One or two short examples to show how the page works.
- A few related links (for example: “lbs to kg”, “oz to grams”).
- One short safety note like “Check values before important use”.

Internal link ideas
Internal links help users and also help search engines understand your tool hub.
- On a “lbs to oz” page, link to “lbs to kg” and “oz to grams”.
- On “cm to inch”, link to “cm to feet” and “mm to inches”.
- On “gallons to liters”, link to “gallons to cups” and “liters to gallons”.
- On any volume page, link back to a main “Kitchen converters” section.
- Add a “See all conversion tools” link back to this main list page.
CSV format
The CSV file uses two columns: name and url. The name comes from the label text in the list above. The URL is the full link, for example: https://www.flashtool.org/convert/lbs-to-oz.
You can import the CSV into:
- Excel or Google Sheets to sort, group, and add notes.
- A headless CMS to auto-create pages or entries.
- A script that builds menus or internal link blocks.
Accessibility and simple language
- Use clear button text like “Convert now” instead of long labels.
- Use short paragraphs and plain words (no complex math terms).
- Make sure labels match what users see, for example “From (km)” and “To (miles)”.
- Check that tools work well on phones and small screens.
Quick checklist before you go live

- Each converter page has a clear H1 title and short intro line.

- All links from this page return a valid page (no 404 errors).
FAQ
Can I change labels or URLs?
Yes. You can rename labels to match your style. You can also change URLs to a different path style. Just keep them clean and simple so people understand them.
Are these live tools?
No. They are suggested links and structure. You still need to build each converter page on your own server or app. This page is for planning and content ideas.
Can I add more converters?
Yes. Add new rows to the CSV or new list items to your page. You can also remove any units that you do not need. The main idea is simple: one clear tool per page.
