What the Kanal Converter does
Kanal Converter: 1 kanal = 505.857 m², so multiply a kanal value by 505.857 to get square metre, or divide to go back. Example: 1 kanal = 505.857 m².
Supply Value, From and To and you get Result, How it was calculated and Reverse conversion back. You can nudge a single number and watch the effect straight away.
Most people who open the Kanal Converter are anyone working across two measurement systems. Having the exact factor matters more than a rough mental estimate.
There is no account, no upload and no server round trip, because the page does the work itself.
The rest of this page documents each field, the method, and a worked example built from the values the kanal converter loads by default.
What do the Kanal Converter fields mean?
The Kanal Converter uses 3 inputs. You do not have to fill everything in before seeing an answer; the starting values already produce one.
| Field | What to enter | Default |
|---|---|---|
| Value | required | 1 |
| From | choose from Square millimetre (mm²), Square centimetre (cm²), Square metre (m²), Hectare (ha), Square kilometre (km²) or Square inch (in²) | Kanal (kanal) |
| To | choose from Square millimetre (mm²), Square centimetre (cm²), Square metre (m²), Hectare (ha), Square kilometre (km²) or Square inch (in²) | Square metre (m²) |
How does the Kanal Converter work?
Both units are converted through area's base unit (m²), so any of the 16 units in the dropdowns can be paired in either direction without loss of accuracy.
The constants come from the SI brochure and the 1959 international yard-and-pound agreement. For quantities defined empirically rather than by treaty, the current CODATA or IAU value is used instead.
Worked example
These are the values the Kanal Converter loads by default, and the result it produces from them. This is the worked example the page starts from, reproduced here so you can check the arithmetic.
| Value | 1 |
|---|---|
| From | Kanal (kanal) |
| To | Square metre (m²) |
| Result | 505.857 m² |
|---|---|
| How it was calculated | 1 kanal = 505.857 m², so 1 × 505.857 = 505.857 m² |
| Reverse conversion | 0.0019768433 kanal (if you meant 1 m²) |
The kanal (South Asian land unit)
A kanal is a traditional land unit used in North India and Pakistan, commonly defined as 605 square yards (505.857 m²), roughly 1/8th of an acre, though exact local definitions can vary.
Worth knowing
- It is especially common in Punjab (both Indian and Pakistani) and in Kashmir/Himachal Pradesh for describing residential plot sizes, where "a 1-kanal house" is a familiar, meaningful size description to local buyers.
- 20 marlas traditionally make up 1 kanal in the same regional system, giving a two-tier system (marla for small plots, kanal for larger ones) analogous to the bigha/biswa relationship used further east.
- As with the other South Asian units here, treat the figure as a widely quoted standard rather than a universal legal definition, and confirm the applicable local standard for any transaction that depends on the exact area.

How to use it
- Put Value.
- Pick a value for From: the options are Square millimetre (mm²), Square centimetre (cm²), Square metre (m²), Hectare (ha), Square kilometre (km²) or Square inch (in²).
- Pick a value for To: the options are Square millimetre (mm²), Square centimetre (cm²), Square metre (m²), Hectare (ha), Square kilometre (km²) or Square inch (in²).
- You will see the result move while you are still editing: that is expected.
- The results panel then shows Result, How it was calculated and Reverse conversion.
- Copy Link puts the current inputs in the URL, so bookmarking it brings the same numbers back.
What this tool does not do
- Repeated conversions compound rounding, so convert once from the original value where possible.
- Factors use the internationally agreed definitions; some industries round them differently.
- It assumes the values you give are already consistent with each other.
- Read the field labels once before trusting the answer; they specify the expected unit.
Frequently asked questions
The form asks for Value, From and To. Every box already holds a working value, meaning you can explore the calculation before committing to real figures.
With the values loaded when the page opens, result comes out as 505.857 m². The figure is derived from the inputs above, so it updates whenever they do.
No. The work runs in JavaScript inside this page, so your values never leave your device. You can confirm it in your browser network tab.
No. There is no account, no usage cap and no trial period. The site is funded by advertising rather than by charging for the tools.
