Why are bigha and katha included?

Because land in South Asia is measured in them, and most converters ignore it. They are here alongside acres and hectares so you do not need a second tool.

Enough decimal places to be useful without pretending to a precision the input does not have. Regional land units genuinely vary by district, so treat those as an approximation.

Does it know South Asian land units?

Yes — katha, bigha, decimal, kanal and marla alongside acres and hectares, at the standard survey values used in Bangladesh and West Bengal. Almost no international converter includes them.

Why do bigha values differ from other sites?

Because bigha genuinely varies by region. This uses 14,400 square feet, the Bangladesh and West Bengal value. Uttar Pradesh and Rajasthan use different ones.

South Asian land units

The standard survey values used in Bangladesh and West Bengal. Almost no international converter carries these, and the units genuinely differ by region — a bigha in Uttar Pradesh is not this bigha.

Unit	Square feet	Also equals
1 katha	720	66.89 m²
1 bigha	14,400	20 katha
1 decimal (shotok)	435.6	1/100 acre
1 acre	43,560	3.025 bigha · 100 decimal
1 hectare	107,639	2.47 acre · 7.48 bigha
1 kanal	5,445	20 marla
1 marla	272.25	1/20 kanal

Temperature, which is not a multiplication

Celsius to Fahrenheit: °F = °C × 9/5 + 32
25 °C = 77 °F
Fahrenheit to Celsius: °C = (°F − 32) × 5/9
98.6 °F = 37 °C
Celsius to Kelvin: K = °C + 273.15
25 °C = 298.15 K

Temperature scales have different zero points, so they convert with an offset rather than a factor. This is why doubling 20 °C does not give 40 °C worth of heat.
