Unit Converter
8 categories incl. Indian land units (acre/hectare/bigha), speed, data & time — with an all-units-at-once table & swap.
1 m =
3.28084 ft
1 m in every unit
💡 Land units vary regionally — the bigha here is the common North-Indian ~2,508 m² value, but your state's revenue records may define it differently. Acre and hectare are universal.
🔄Eight categories, every unit at once
Length, weight, area, volume, speed, time, data storage, and temperature — with the units India actually uses: acre, hectare, bigha, cent, and guntha for land, km/h for speed, GB vs GiB for storage. Convert one value and the side table shows it in every unit of the category simultaneously; the ⇄ button flips direction instantly.
🧮How conversions work
Every unit is defined by its ratio to a base (meter, kilogram, square meter…), so any pair converts through one multiplication. Temperature is the exception — °C, °F, and K have shifted zeros, so it uses the proper affine formulas rather than a factor.
💡Conversions students actually need
- 1 hectare = 2.471 acres = 10,000 m² — the land-record trio.
- 1 GB (decimal, what drives advertise) = 0.931 GiB (binary, what Windows shows) — the missing-storage mystery solved.
- km/h ÷ 3.6 = m/s — the physics-exam constant.
- 1 mile = 1.609 km, 1 inch = 2.54 cm exactly, 1 pound = 453.6 g.
- Bigha and guntha vary by state — always confirm against local revenue records for legal documents.
💡 Frequently Asked Questions
How many acres are in a hectare?+
1 hectare = 2.471 acres, and 1 acre = 0.405 hectares (4,046.86 m²). Both are standard worldwide, unlike bigha which varies regionally.
How big is a bigha?+
It varies by state — this converter uses the common North-Indian value of about 2,508 m² (0.62 acre), but Rajasthan, Bengal, and Assam each define it differently. For legal land matters, verify against your state's revenue standard.
Why does my 1 TB drive show only 931 GB?+
Manufacturers count in decimal (1 TB = 10¹² bytes); operating systems often count in binary (1 TiB = 2⁴⁰ bytes) while displaying 'GB'. 10¹² ÷ 2³⁰ ≈ 931 — no storage is missing. The data category converts both systems.
How do I convert km/h to m/s?+
Divide by 3.6 (because 1 km = 1000 m and 1 h = 3600 s). So 72 km/h = 20 m/s — the conversion every physics numerical expects you to know cold.
Why does temperature convert differently from other units?+
Because the scales have different zero points, not just different sizes: °F = °C × 9/5 + 32, K = °C + 273.15. A simple ratio would give wrong answers everywhere except zero.
