Metric to Imperial Converter
Convert seamlessly between metric and imperial units. Perfect for international cooking, travel, construction projects, or understanding measurements from different countries.
What is the difference between metric and imperial systems?
The metric system (SI) uses base-10 units: meters for length, kilograms for mass, liters for volume. It's used by most countries worldwide. The imperial system uses feet, pounds, gallons, etc., and is primarily used in the US, UK, and a few other countries. Metric is easier for calculations due to decimal-based conversions (e.g., 1 km = 1000 m), while imperial uses irregular conversions (e.g., 1 mile = 5280 feet).
How do you convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. To convert Fahrenheit to Celsius: °C = (°F - 32) × 5/9. Examples: 0°C = 32°F (freezing point), 100°C = 212°F (boiling point), 20°C = 68°F (room temperature), 37°C = 98.6°F (body temperature). Remember: Fahrenheit has smaller degrees, so the range is larger.
How many pounds are in a kilogram?
1 kilogram = 2.20462 pounds (approximately 2.2 lbs). To convert: kg × 2.2 = lbs; lbs / 2.2 = kg. Examples: 50 kg ≈ 110 lbs, 70 kg ≈ 154 lbs, 100 kg ≈ 220 lbs. For body weight, most people round to the nearest pound. This is one of the most common metric-imperial conversions needed for international travel, shipping, and medical records.
Why doesn't the US use the metric system?
The US officially adopted the metric system in 1975 but never mandated its use. Reasons for slow adoption: High cost to replace infrastructure, signage, and tools; public resistance to change; established industries using imperial measurements. The US does use metric in science, medicine, and military. Some sectors like soda (2-liter bottles) and track & field use metric. Despite this, imperial measurements remain dominant in daily life, construction, and cooking.
