| Conversion | Formula | Example |
|---|---|---|
| Celsius to Fahrenheit | °F = (°C × 9/5) + 32 | 20°C = 68°F |
| Fahrenheit to Celsius | °C = (°F - 32) × 5/9 | 68°F = 20°C |
| Celsius to Kelvin | K = °C + 273.15 | 20°C = 293.15K |
| Kelvin to Celsius | °C = K - 273.15 | 293.15K = 20°C |
Mass is the amount of matter in an object (measured in kg, g, etc.), while weight is the force exerted by gravity on that mass (measured in N). In everyday use, "weight" often refers to mass.
The metric system (SI) is used worldwide, while the imperial system is primarily used in the US. Different systems developed historically in different regions before global standardization.
Conversions use standardized conversion factors. For most practical purposes, they're accurate to 6+ decimal places. Temperature conversions are exact based on their formulas.
