About Measurement Converters
Measurement converters handle the five fundamental physical quantities encountered in everyday life: length, weight, area, volume, and temperature. Together they cover the most frequent unit conversion needs for Indian users — from body height and weight to plot sizes, cooking volumes, and weather temperatures.
Why measurement conversions matter in India
India's metric adoption in 1957 was official, but cultural usage remains split. Body height is discussed in feet and inches at clinics, gymnasiums, and matrimonial listings — even though the official medical unit is centimetres. Real estate agents quote flat sizes in square feet; RERA mandates reporting in square metres; buyers compare both. Petrol is sold in litres; milk in 500 ml or 1 L pouches; medicine in millilitres; but imported recipe videos measure in cups and tablespoons. No other country uses quite this mix.
The measurement converters on this platform handle all of these transitions without requiring mental arithmetic or memorising a dozen conversion factors.
Key converters in this category
The Length Converter is the most general-purpose tool — useful for height conversions, room dimensions, fabric measurements, and technical drawings. The Weight Converter covers everything from postal parcel limits to body weight, with traditional Indian units such as tola (gold measurement) and maund included for completeness.
The Area Converter handles residential and agricultural land sizes across metric, imperial, and regional Indian units. The Land Area Converter extends this with regional bigha, guntha, cent, and kanal units that vary by state. The Volume Converter covers both dry and liquid volumes, bridging metric litres to US cups and imperial fluid ounces for international recipe conversion.
The Temperature Converter covers Celsius, Fahrenheit, Kelvin, and Rankine — essential for cooking (oven temperatures in °F on international recipes), science (Kelvin in chemistry and physics), and medical reference.
Precision and standards
All conversion factors in this category use the exact internationally defined values where they exist (SI, IEEE, NIST). Derived values are carried to at least 6 significant figures — sufficient for engineering, commercial, and scientific purposes.
Frequently Asked Questions
The Measurement category includes converters for length, weight, area, volume, and temperature — the five fundamental physical quantities used in everyday life, engineering, and science. Each converter handles all major metric, imperial, and Indian traditional units. Additional converters for speed and pressure are available in the Time & Speed and Energy & Power categories respectively.
The [Length Converter](/length-converter/) covers metric units (millimetre, centimetre, metre, kilometre), imperial/US units (inch, foot, yard, mile), and nautical units (nautical mile). It also includes the micron and the ångström for scientific use. The most common conversions in India are centimetres to feet/inches (height) and kilometres to miles (international distances).
1 kilogram equals approximately 2.20462 pounds. To convert, multiply your kilogram value by 2.20462. For example, 70 kg × 2.20462 = 154.32 lbs. The [Weight Converter](/weight-converter/) handles this instantly, along with conversions between grams, tonnes, ounces, and traditional Indian units such as tola and maund.
A metric tonne (t) equals exactly 1,000 kilograms or approximately 2,204.62 pounds. A short ton (used in the United States) equals 2,000 pounds or approximately 907.18 kilograms. A long ton (UK imperial) equals 2,240 pounds or approximately 1,016.05 kilograms. In India, the metric tonne is the standard — specifications for cargo, agriculture, and commodities use metric tonnes unless otherwise stated.
The formula is °F = (°C × 9/5) + 32. For example, 37°C (normal body temperature) = (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F. The [Temperature Converter](/temperature-converter/) also handles Kelvin and Rankine, which are used in scientific contexts. A quick mental shortcut: multiply by 2 and add 30 (gives a rough estimate, not exact).
1 litre equals exactly 1,000 millilitres. Litres are used for larger liquid volumes — milk, petrol, packaged water — while millilitres are used for smaller amounts such as medicine doses, cooking ingredients, and packaged beverages under 1 litre. The [Volume Converter](/volume-converter/) also converts to US cups, fluid ounces, gallons, and UK imperial units, which matter when using international recipes.
Indian traditional land area units vary by region. The [Land Area Converter](/land-area-converter-india/) covers standard units — 1 acre = 4,046.86 square metres; 1 hectare = 10,000 square metres — plus regional Indian units: 1 guntha (Maharashtra/Karnataka) = 101.17 square metres; 1 bigha varies by state (approximately 1,333–2,500 square metres). Always verify the regional definition of bigha before using it in legal or commercial contexts.
India officially adopted the metric system in 1957, but legacy imperial units remain widespread. Body height is commonly expressed in feet and inches (not centimetres) in everyday conversation. Real estate uses square feet alongside square metres and acres alongside hectares. Body weight is often discussed in kilograms but clothing sizes use inches. These dual usages are cultural habits, not legal standards — the legal standard in India is metric.
All conversion factors are based on exact international definitions where they exist. 1 inch = 0.0254 metres exactly (defined in 1959 by international agreement). 1 pound = 0.45359237 kilograms exactly. 1 calorie = 4.184 joules exactly. For derived units, factors are given to at least 6 significant figures. These converters are suitable for engineering, academic, and commercial use.
Residential real estate in Indian cities typically uses square feet for apartment sizes and square metres in builder specifications (mandated by RERA). Urban plot sizes use square yards in North India and square metres or cents in South India. The [Area Converter](/area-converter/) handles all of these, including the conversion between square feet and square metres (1 sq ft = 0.0929 sq m), which is essential for comparing international property listings.
India uses the Celsius scale as the official temperature standard. Weather forecasts, food safety regulations, medical references, and industrial specifications all use Celsius. Fahrenheit is occasionally encountered in older imported documentation and informal contexts. The Kelvin scale is used in scientific and technical standards. The [Temperature Converter](/temperature-converter/) converts between all four scales: Celsius, Fahrenheit, Kelvin, and Rankine.
Divide the km/h value by 3.6 to get m/s. For example, 90 km/h ÷ 3.6 = 25 m/s. This conversion appears in physics problems, vehicle dynamics calculations, and wind speed specifications. The reverse: multiply m/s by 3.6 to get km/h. The [Speed Converter](/speed-converter/) in the Time & Speed category handles this and additional units including mph, knots, and feet per second.
