symbols of units named after a person are capitalized
(e.g., ampere and A).
What are the rules to be followed in writing the symbols of units?
i) The symbols of the units named after scientists should be
written by the initial capital letter
. E.g. N for newton, H for henry, A for ampere and W for watt. ii) Small letters are used as symbols for units not derived from a proper noun. E.g. m for metre, kg for kilogram.

- The symbols used for the units which are named after the name of any scientist should be written by a capital letter.
Should units be italicized?
2. The overall rule is that
symbols representing physical quantities or variables are italic
, but symbols representing units, mathemathical constants, or labels are roman.
What are the rules for writing units?
- The symbols of the units named after scientist should be written by a capital letter.
- For example : N for newton, H for henry, W for watt.
- Small letters are used as symbols for units not derived from a proper name.
- For example : m for metre, kg for kilogram.
How do you represent units?
Units: The names of all units start with a lower case letter except, of course, at the beginning of the sentence. There is one exception: in “degree Celsius” (
symbol °
C) the unit “degree” is lower case but the modifier “Celsius” is capitalized. Thus, body temperature is written as 37 degrees Celsius.
What is the SI unit of length?
| Base quantity Base unit | length l, x, r, etc. metre | mass m kilogram | electric current I, i ampere | thermodynamic temperature T kelvin |
|---|
How do you write units and values?
These include: – Values are written as a number followed by a space (representing a multiplication sign)
and a unit symbol
, e.g. 2.4 kg or J. This convention also applies to the per cent sign (%).
What things should be remember while writing the symbol of unit?
Explanation: – Symbols for units are written in lower case (e.g., “m”, “s”, “mol”), except
for symbols derived from the name of a person
. For example, the unit of pressure is named after Blaise Pascal, and is written “Pa”, even though the unit itself is written “pascal” (see below).

Do you put space between number and unit?
There is a space between a number
and a unit of measurement e.g. 20 mg – except for temperatures e.g. 20°C and percentages e.g. 20% (or in text use 20 per cent). When giving a range do not repeat the unit, e.g. 5 to 8 mg and not 5 mg to 8 mg. Use the word ‘to’ in text, not a dash.
What is a SI number?
The SI base units are the standard units of measurement defined by the International System of Units (SI) for the
seven
base quantities of what is now known as the International System of Quantities: they are notably a basic set from which all other SI units can be derived.
Is kg/m s 2 a derived unit?
The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measurement of frequency), but the rest merely reflect their derivation: for example, the square metre (m
2
), the SI derived unit of area; and the kilogram per cubic metre (kg/m
3
or kg⋅m
− 3
), the SI derived unit of density.
What are the 7 basic SI units?
- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)
