Converter tools

Free unit, timestamp, time and clothing size converters, instant results

Convert measurements, Unix timestamps, durations and sizes in one step without creating an account or copying values into a separate spreadsheet. The most common conversion searches covered: metric and imperial units; Unix epoch timestamps across 8 timezones with live clock; time unit translation from seconds to years; and international clothing and shoe size charts for US, UK, EU, FR, IT, DE, ES and JP.

Unit Converter Convert instantly between metric, imperial and international units: length, weight, temperature, volume, area, speed. Epoch Converter Convert Unix timestamps to readable dates in 8 timezones, or dates to timestamps. Live clock, relative time, ISO 8601. Time Converter Convert instantly between all time units: seconds, minutes, hours, days, weeks, months, years, and more. Clothing Size Converter Convert clothing and shoe sizes between US, UK, EU, FR, IT, DE, ES and JP. Includes men, women and body measurements.

Instant conversion with no lookup or spreadsheet needed

Conversion lookups are quick searches, you have one value and need one answer. These tools put the result immediately next to the input, support direct keyboard entry, work on mobile without zooming and continue working offline after the first load.

Measurements and everyday units

Unit conversions come up in cooking, construction, science, travel and international commerce, and the same quantity can be expressed in a dozen different ways depending on country and context. Length, weight, temperature, volume, area and speed are the categories people convert most often. Seeing all equivalent values at once, rather than converting one target at a time, makes it faster to pick the right unit for the situation.

Timestamps, timezones and time durations

Unix timestamps are used throughout web development, database records and server logs. Reading one means converting a number into a human-readable date, across the right timezone. Time duration conversions, how many seconds in three years, how many weeks in a project budget, come up in scheduling, billing and scientific work. Both directions are supported: timestamp to date, date to timestamp, any time unit to any other.

International clothing and shoe sizes

Clothing and shoe sizes follow different scales in the US, UK, EU, FR, IT, DE, ES and JP, a size 10 in one system is a different physical measurement in another. Shopping internationally or gifting across size systems without a reliable reference chart leads to returns. Body measurements (chest, waist, hips) provide a more accurate anchor than size labels alone.

All conversions run offline after loading

Conversion tables are built into each page. Once loaded, no network connection is needed to calculate results. No values are sent to a server, making these tools safe to use on restricted or metered connections.
