°F=°C×95+32°F = °C \times \tfrac{9}{5} + 32

Temperature scales have different zero points, so they use a formula rather than a single factor.

Ejemplos resueltos

Convert 1 mile to kilometres

1 mile is exactly 1609.344 metres.

So 1 mile = 1.609344 km.

Easy: 480 cm to m

100 cm = 1 m, so divide by 100.

480 cm ÷ 100 = 4.8 m.

Medium: 107 pounds in kg

1 lb = 0.45359237 kg exactly.

107 × 0.45359237 = 48.534384 kg (about 48.5 kg).

Hard: 51 kg in stone and pounds

1 stone = 14 lb = 6.35029318 kg, so 51 kg ÷ 6.35029318 = 8.031125 st.

The whole part is 8 stone. The 0.031125 st left over × 14 = 0.44 lb.

So 51 kg ≈ 8 st 0.44 lb (or 112.44 lb in total).

Errores frecuentes

  • Multiplying when you should divide: going to a bigger unit (cm → m) makes the number smaller.
  • Mixing US and UK units: a US gallon is 3.785 L, a UK gallon 4.546 L. This converter uses US cups, pints, quarts and gallons.
  • Reading 8.03 stone as 8 st 3 lb: the decimal part is a fraction of a stone; 0.03 st is about 0.44 lb.
