The formula is °F = (°C × 9/5) + 32. For example, 100°C = 212°F (boiling point of water) and 37°C = 98.6°F (normal body temperature). The reverse is °C = (°F − 32) × 5/9.
1 mile = 1.60934 kilometers. Conversely, 1 kilometer = 0.62137 miles. A quick mental trick: multiply miles by 1.6 to get an approximate km value.
1 kilogram = 2.20462 pounds. To convert kg to lbs, multiply by 2.205. To convert lbs to kg, divide by 2.205 (or multiply by 0.4536).
UTC (Coordinated Universal Time) is the primary global time standard. All other time zones are expressed as offsets from UTC — for example, New York is UTC−5 (or UTC−4 in summer), and London is UTC+0 (or UTC+1 in summer during BST).
Yes. The converter uses your browser's built-in Intl API, which automatically applies the correct DST offset for any date you select — including historic dates and future dates where DST rules are known.
