Unit Converters

Accurate unit converters with clearly stated factors: length, weight, temperature, data storage (decimal and binary units) and land area including guntha, acre, hectare and square feet.

Converting units accurately

Every converter uses international definitions, such as 1 inch = 2.54 cm and 1 pound = 0.45359237 kg, and shows the value in all units at once. The Data Storage Converter explains why a “1 TB” drive appears as about 931 GB on a computer: decimal and binary units differ.

The Land Area Converter handles local units such as guntha, acre, hectare, cent and square feet. Local definitions can vary by state, so confirm important figures with official land records.

Quick tips

  • 1 guntha = 1,089 square feet; 40 guntha = 1 acre.
  • Round only at the end of a calculation, not in between.

Unit Converters: common questions

Why does my 1 TB drive show less space?

Manufacturers use 1 TB = 1,000,000,000,000 bytes, while many operating systems divide by 1024, showing about 931 GiB. No space is missing.
