I work on documents where scientific units are used, and need to know how to
insert a 'thin space' between numbers and units, as required by the
International System of Units. Is this possible in Word?
Click Insert > Symbol (in Word 2007, Insert > Symbol > More Symbols). In the
dialog, click the Special Characters tab. It offers a 1/4 em space (probably
what you want), an en space, and an em space.
If that doesn't do what you want, you can alter the spacing with greater
precision this way:
- Type an ordinary space between the number and unit.
- Select the space character.
- Right-click, select Font, and click the Character Spacing tab.
- Set the Spacing box to Condensed, and enter a measurement in points by which
to reduce the width of the space. You can enter an integer or a number with one
or two decimal places.
Unlike the special spaces from the symbol dialog, this method takes no account
of the font size; the reduction is an absolute value in points.
