Frequently asked questions
Why do metric and imperial units give slightly uneven numbers?
Metric units (mm, cm, m, km) scale by powers of ten, so conversions between them are exact and clean. Imperial units (inches, feet, yards, miles) were standardized separately and don't align to round metric values, which is why you see figures like 2.54 or 1.60934 instead of whole numbers.
How many feet are in a meter?
1 meter is approximately 3.28084 feet. This calculator shows that conversion (and every other common unit) instantly as soon as you enter a value.
