Units Master Help

Supported Units of Measurement

• length units: mils, points, picas, inches, links, feet, yards, rods, chains, furlongs, miles, fathoms, nautical miles, millimeters, centimeters, decimeters, meters and kilometers.

• area units: square mils, square inches, square links, square feet, square yards, squares, square rods, square chains, acres, square miles, townships, square millimeters (mm²), square centimeters (cm²), square decimeters (dm²), square meters (m²), ares, hectares and square kilometers (km²).

Calculate and convert not only length or area units but mix area and length units in your calculataions, e.g. you can divide 100sq.yd by 15ft, add 18sq.ft and 9yd×7.5ft and much more

Entering fractional and decimal values and units

Shortcuts/Hotkeys for Mac and Windows versions

Entering fractional and decimal values and units

Options that make Units Master unique and different from other calculators:

1. Unlike many other calculators and converters, you may enter any combinations of units

For example, you may enter 1yd3ft2in, 2m15cm4mm, 1_3/4yd5ft, etc.





2. With Units Master you may enter dimensional values in any order.

It does not matter if you enter the larger or the smaller dimension first, the app shows you the correct answer in both cases. For example, it does not matter if you enter feet before inches 2ft3in or inches before feet 3in2ft.

Tips: With Units Master you don't have to waste time by entering the addition operator (+) between units. Just enter the values one by one and press =.

2.5yd 3ft 4.5ft 25in 3_1/2ft = 2.5yd + 3ft + 4.5ft+ 25in + 3 1/2ft = 20ft7in



3. You may enter whole, decimal and fractional values for all imperial and metric units.

For example, you may enter 3.5ft, 5/8in, 3/4mi, 1 3/4 yd, 0.8km, 7/8m, 10.8cm, etc

4. You may mix US and metric units in one equation.

Customise the output of results

Units Master provides advanced customization for the way you need to have the results. To tailor the app to your needs, click Settings in the top-left corner. The Settings window gives you all the freedom you need to show the output format.

Customization Options

Default Output Unit
The Length output unit and the Area output unit are specified independently of each other
You may choose if you want to see the results in US units or Metric units. In case you choose 'US' or 'Metric' units, you can also specify the desired unit. For more info see the List of supported units
In case you select 'Auto' the results will be shown in the units of the expression.

Number of decimal places
This option allows you to specify on how many decimal places you want to round the result. Depending on you needs, you can choose from 0 to 8 decimal places. Choosing more decimal places increases the precision of the calculation result. In case of '0', the results will be shown as a whole number.

Round fraction to nearest
This option is very helpful, when the precision isn’t necessary and you prefer rounded and easier-to-work with values instead of exact fractions. You may choose to round the results to the nearest 1/2, 1/4, 1/8, 1/12, 1/16, 1/32, 1/64, 1/128, 1/256. In case, you do not need to round fractions, just select "-".

Output Format
As the app supports calculation with both fractions and decimals, you may choose how you want to see the result. Here you have four options:
'Fractions + Decimals' - no matter if you enter values as fractions or decimals, the result will be displayed in both formats.
'Fractions' - regardless of whether the expression uses fractions or decimals, the result is shown as a fraction.
'Decimals' - results are always displayed as decimals, even when fractions were used in an expression.
'Auto' - the output format follows the logic of what was used in the expression. If all values in the expression are fractions, the result is shown as a fraction. If the expression contains only decimals, the result is displayed as a decimal. If the expression contains both fractions and decimals, the result is displayed in a fractional form.

Feet and inches symbols
While users and industries have different preferences for how feet and inches are displayed - some prefer symbols ′ and ″, others prefer letters ft and in - this option gives you the choice to specify the display format for feet and inches.
