Are these unit converters accurate?
Yes. They use the exact international definitions (for example, 1 mile = 1.609344 km and 1 pound = 0.45359237 kg) and only round the final number for display.
Can I convert in both directions?
Yes. Every converter works both ways: use the swap button or pick the units you need, and the result updates as you type.
Do the converters work on my phone?
Yes. They work on any phone, tablet or computer, and the answer appears as you type.
How many decimal places should I use?
Results keep enough precision for technical work. For everyday use, round to what you need; for distances and weights, one or two decimal places is usually plenty.
