Unit Conversion Tools

Tools for Unit Conversion

It's simple to convert between metric, U.S., and Imperial measurements with these tools. Use one of these calculators to quickly convert units such as length, weight, volume, temperature, cooking units, or more. The resulting accuracy is based on the accuracy of the original measurement.

How to use unit conversion calculators
The value being converted is entered, and the corresponding source and destination units selected. Make sure the right measurements system is chosen-cups, ounces, and gallons can mean very different things. When converting ingredients by volume, use the cooking tool that accommodates your ingredient because equivalent volumes of different foods may have different weights.

How precise are unit conversions?

Many unit conversions can be calculated with just mathematical conversion factors, but others need extra factors depending on properties such as density. For example, converting between cups and grams requires separate calculation for different ingredients like butter, sugar, flour and liquid foodstuff. Temperature conversion requires an offset and scale factor, and currency depends on current exchange rates (without fees).

Choosing the correct calculator

A calculator that correctly suits your needs may not match the title. Be sure to use a unit converter that fits the information field labels, the formula described, and directions given, and do not just click the first result.

Get the Best Result

Have the original measurement and unit available so it can be checked. Avoid over or under presenting decimals, and only round the final result.

Verify the Result

Estimate mentally what the answer will look like before relying on the calculator's output. For instance, consider a meter to feet conversion. It is slightly longer than one yard, which has three feet in a meter to be 39.37 inches. Similarly, an inch is always 2.54 centimeters and a kilometer is about a mile on a map.

Where are unit conversion errors common?

Misremembering what the Imperial system was versus what U.S. Measurements are commonly used for in the U.S. Or mixing up what weight is versus what volume is. It is also very common to mix the source and destination fields or to round too soon.

Commercial & technical uses

This is helpful for school and home use, for cooking, traveling, and all those general calculation purposes. However, for engineering, laboratory use, industry manufacturing, medical and regulatory industries, use a unit that meets professional conversion standards or check what is specified by your specific manufacturer for calibrated instruments or round as appropriate for your field.

Simple unit conversion work flow

1. Input the original value.

2. Choose the correct source and destination units.

3. Calculate the value.

4. Double check the result;

5. Estimate value and verify the result before use.

6. Always specify the unit when stating the converted result.
