Length Converter
Convert between all standard units of length and distance:
Metric: Millimeter (mm) · Centimeter (cm) · Meter (m) · Kilometer (km) Imperial/US: Inch (in) · Foot (ft) · Yard (yd) · Mile (mi) Other: Nautical mile · Light year · Astronomical unit
Most common conversions:
| From | To | Formula |
|---|---|---|
| Centimeters | Inches | cm ÷ 2.54 |
| Meters | Feet | m × 3.28084 |
| Kilometers | Miles | km × 0.621371 |
| Miles | Kilometers | miles × 1.60934 |
| Feet | Meters | ft × 0.3048 |
Who uses it: International travelers checking road distances, architects switching between metric and imperial measurements, athletes tracking performance in different units, e-commerce sellers providing product dimensions in multiple formats.
Weight Converter
Convert between all standard units of mass and weight:
Metric: Milligram (mg) · Gram (g) · Kilogram (kg) · Metric ton (t) Imperial/US: Ounce (oz) · Pound (lb) · Stone (st) · US ton · UK (long) ton
Most common conversions:
| From | To | Formula |
|---|---|---|
| Kilograms | Pounds | kg × 2.20462 |
| Pounds | Kilograms | lb × 0.453592 |
| Grams | Ounces | g ÷ 28.3495 |
| Stone | Kilograms | stones × 6.35029 |
Who uses it: People tracking body weight in different units, nutritionists calculating food quantities, international shipping companies converting package weights, medical professionals recording patient measurements.
Pakistan-specific note: Pakistan officially uses the metric system, but traditional units like seer (approx. 933 grams), maund (approx. 37.3 kg), and tola (approx. 11.7 grams, used for gold) are still used in local trade and agriculture. These are not universal SI units but may be added to SmallSEOToolsn’s converter as regional options.
Area Converter
Convert between all standard units of area:
Metric: Square millimeter · Square centimeter · Square meter (m²) · Square kilometer (km²) · Hectare (ha) Imperial/US: Square inch · Square foot · Square yard · Acre · Square mile South Asian: Marla · Kanal · Acre (widely used in Pakistan for land measurement)
Most common conversions in Pakistan:
| From | To | Equivalent |
|---|---|---|
| 1 Marla | Square yards | 30.25 sq yards |
| 1 Kanal | Marla | 20 Marla |
| 1 Acre | Kanal | 8 Kanal |
| 1 Acre | Square meters | ~4,047 m² |
Unique insight: For Pakistani users, area conversion is among the most practically important unit conversions — particularly for real estate. Property sizes in Pakistan are commonly advertised in Marla and Kanal, but bank valuations, legal documents, and international investors often require square meters or acres. An accurate Marla-to-square-meter converter is genuinely high-value content for Pakistani audiences that almost no global converter tool covers.
Temperature Converter
Convert between the three major temperature scales:
Celsius (°C) — Standard in Pakistan, most of the world, and science Fahrenheit (°F) — Used primarily in the United States Kelvin (K) — Used in scientific contexts; 0 K = absolute zero = −273.15°C
Conversion formulas:
| From | To | Formula |
|---|---|---|
| Celsius | Fahrenheit | (°C × 9/5) + 32 |
| Fahrenheit | Celsius | (°F − 32) × 5/9 |
| Celsius | Kelvin | °C + 273.15 |
| Kelvin | Celsius | K − 273.15 |
Common reference points:
| Temperature | Celsius | Fahrenheit |
|---|---|---|
| Water freezes | 0°C | 32°F |
| Body temperature | 37°C | 98.6°F |
| Room temperature | 22°C | 71.6°F |
| Water boils | 100°C | 212°F |
| Pakistan summer heat | 45°C | 113°F |
Power Converter
Convert between electrical and mechanical power units:
Watt (W) · Kilowatt (kW) · Megawatt (MW) — Electrical and SI standard Horsepower (hp) — Common for vehicles and machinery BTU/hour — Used for HVAC and air conditioning systems
Most common conversions:
| From | To | Equivalent |
|---|---|---|
| 1 Horsepower | Watts | 745.7 W |
| 1 Kilowatt | Horsepower | 1.341 hp |
| 1 Ton (HVAC) | BTU/hour | 12,000 BTU/h |
| 1 Ton (HVAC) | Kilowatts | 3.517 kW |
Pakistan-specific context: Air conditioning capacity in Pakistan is commonly expressed in “Tons” (1 ton = 12,000 BTU/hour = 3.517 kW). When comparing inverter AC specifications or electricity consumption, converting between tons and kilowatts is a practical daily need for Pakistani consumers and businesses.

- USD to PKR — essential for freelancers, importers, and investors
