1 meter equals approximately 3.28084 feet. To convert meters to feet, multiply the length value in meters by 3.28084. To convert feet to meters, multiply by 0.3048.
Multiply the temperature in Celsius by 9/5 (or 1.8) and add 32. Formula: °F = (°C * 9/5) + 32. For example, 100°C = (100 * 1.8) + 32 = 212°F.
