Basic Measurements Converters

Converters for Basic Measures

Basic measures, such as weight, length, or volume, are the ones people use most often. That's why a tool that helps quickly convert grams to pounds or degrees Celsius to Fahrenheit can be very handy.

This page features the list of the most useful basic converters. These converters are the most popular on

Weight and Mass Units Converter

Strictly speaking, weight is not the same as mass. However, in everyday life we rarely distinguish the two. That's why we decided not to complicate thing here and made an easy to use Weight and Mass Converter.

Our weight converter features metric (SI), avoirdupois (U.S), Troy, and Apothecaries units. There are also national units of India, China, Hong Kong, Japan, and Thailand. Even though most of these countries have switched to metric system already, people still use national pre-metric units there occasionally.

If you are looking for more national weight units or old units of weight that are no longer in use today, please check our Ancient and Historical Weight Converter.

Distance and Length Units Converter

Length or distance is another measure that everyone uses daily. It makes our Distance and Length Converter the most requested among our site visitors.

Our length converter features metric (SI), U.S. customary, U.S. surveyors's, and British imperial units. We feature nautical units: International nautical, U.S. nautical, and British imperial nautical. There are national units of Latin American countries (Spanish), China, Hong Kong, Japan, and Thailand. These units are still in use occasionally. We also added some technical units from various science fields like optics, typography, computer equipment, astronomy, and more.

Capacity and Volume Units Converter

Capacity is another commonly used measurement. Of course we have our Capacity and Volume Converter available too.

Our volume converter features metric (SI), U.S. liquid, U.S. dry, British imperial, and U.S. derivatives of length units. We added special units like English wine cask units, lumber measure, astronomical, ship tonnage, and cooking (U.S., international, and Australian). There are national units of China, Japan, and Thailand.

Area Units Converter

Everyone knows that area is not an indipendent measurement, but a derivative of length. Nevertheless, converting area units is often harder than units of distance. That's why our Area Converter is used very often

Our area converter features metric (SI) and U.S. customary units as well as various historical units still in use today. There are also national units of China, Japan, and Thailand.

Units of Speed Converter

Speed is another very common measurement we use every day. Even though it is very common, converting units of speed is not straightforward at all. Are you able to quickly convert miles per hour to minutes per mile? Calculations like this are hard to make in one's head without a calculator. That's when our Units of Speed Converter becomes handy.

Our speed converter features metric (SI), British and U.S., and nautical units. We also provide "reverse" units that runners and joggers often use like minutes per kilometer or seconds per mile. We've added a couple of speed constants and examples like speed of sound in gas and speed of light in vacuum.

Temperature Converter

One seldom needs to make temperature conversion. It usually happens ony when you travel abroad or watch an international news and stumble upon Celsius (if you are from the U.S.) or Fahrenheit (if you are from the rest of the world). What does it mean +25°C, is it hot or cold? If you need a quick answer to a question like this, use our Temperature Converter.

Our temperature converter includes five temperature scales used today as well as four historical scales.
