Converters that know Indian units
Most converters online stop at metres and feet. Ours include the land units used on Indian sale deeds — cent (Kerala, Tamil Nadu, Andhra), bigha and katha (North and East India), guntha (Maharashtra, Karnataka), ankanam (Andhra, Telangana), marla and kanal (Punjab, Haryana, J&K) and ground (Chennai) — plus the Indian number system (lakh, crore) and IST time-zone converters.
Converters that know Indian units
Global converter sites stop at acres and hectares. India measures land in cent, dismil, guntha, ankanam, ground, gaj, bigha, katha, marla and kanal — and the bigha alone has a different size in every state. These pages carry the local values, show the formula both ways with worked examples, and include state-wise tables so a plot quoted in Bihar bigha can be compared with one in Rajasthan bigha on a per-square-foot basis.
Everyday measurements
Height in cm for a form when you only know feet and inches; kilograms to pounds for a gym chart; litres to millilitres for a recipe; KB, MB and GB in both decimal and binary counting; Celsius to Fahrenheit for a fever reading; and the Indian number system — lakh, crore, arab — against million, billion and trillion. The number-to-words pages spell amounts for cheques, DDs and invoices in Indian and international styles, with Hindi words for Hindi cheque books.
Developer and student conversions
Binary, decimal, octal and hex with the division method explained; text to binary; Roman numerals with year charts; and IST to EST, PST and GMT time differences for calls and deadlines.
