Frequently asked questions
- How do I convert cm to inches?
- Pick Length, enter your value, pick cm in From and in in To. 1 inch = 2.54 cm, so 175 cm ≈ 68.9 in.
- How do I convert kg to lbs?
- Pick Weight, enter your value, pick kg → lb. 1 lb = 0.45359237 kg, so 70 kg ≈ 154.3 lb.
- How do I convert Celsius to Fahrenheit?
- Pick Temperature, enter your value, pick C → F. The math: °F = °C × 9/5 + 32. So 20°C = 68°F and 100°C = 212°F.
- What is 5'10" in cm?
- 5 feet 10 inches = 70 inches × 2.54 = 177.8 cm. In our tool, convert 70 in → cm to get the same result.
- How do I convert metres to feet?
- Pick Length, m → ft. 1 m = 3.2808 ft, so 6 m ≈ 19.69 ft.
- Can I convert litres to gallons?
- Volume conversions aren't in this v1 — the tool covers length, weight and temperature. We'll add volume in a future update.
- What's the difference between US and UK gallons?
- 1 US gallon ≈ 3.785 L; 1 UK (imperial) gallon ≈ 4.546 L. They're not interchangeable, which is why our future volume converter will distinguish them.
- How accurate are the conversions?
- We use the official SI factors (e.g. 1 lb = 0.45359237 kg exactly). The display rounds to a sensible number of digits but the internal math is full double precision.
- Can I convert multiple values at once?
- This tool focuses on a single value. For lists, change the input value — the result updates instantly, so you can run through a list quickly.
- Can I save a favourites list?
- Not yet — the tool resets to length on every visit. The conversion runs as you type, so swapping families and units is just a couple of clicks.
