The second, symbol s, is the SI unit of time. It is defined by taking the fixed numerical value of the cesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom, to be 9 192 631 770 when expressed in the unit Hz, which is equal to s-1.
This system is called DMS (degrees, minutes, seconds). The symbol for degrees is °, for minutes is ', and for seconds is “.
multiplication sign (×)
The second (symbol: s) is the unit of time in the International System of Units (SI), historically defined as 1⁄86400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each (24 × 60 × 60 = 86400).
For example 15 minutes (¼ hour) equals . 25, 30 minutes (½ hour) equals . 5, etc.
To convert any fraction to decimal form, we just need to divide its numerator by the denominator. In this case, if we convert 15 minutes to hours we write it as 15/60 because 1 hour = 60 minutes. This means 15 minutes can be written as 0.25 hours in the decimal form.

The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity) ...
The SI unit of time is the second, which has been further accurately defined as “the time interval equal to 9192631770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom (13th CGPM, 1967).” In any case, the unit second is often ...
A unit symbol is written in lower case, except that its initial letter is capitalized if the unit is named after a person. These are symbols, not abbreviations or contractions: Do not use periods or other punctuation. To avoid confusion with math symbols ("variables"), do not italicize unit symbols.

Is a dot a times symbol?
In some countries, such as Germany, the primary symbol for multiplication is the "dot operator" ⋅ (as in a⋅b). This symbol is also used in algebraic notation to resolve ambiguity (for instance, "b times 2" may be written as b⋅2, to avoid being confused with a value called b2).
The symbols Δt and ΔT (spoken as "delta T") are commonly used in a variety of contexts.
...
For instance, we know that:

- the "30 minutes" family.
30 minutes is half an hour, we say "half past" or "thirty". 15 minutes is quarter of an hour, we say "quarter past" or "fifteen" or "quarter to" or "forty-five". We never say "half to". It's twenty-eight minutes to twelve.
What is 25 minutes as a decimal?
25 minutes = 0.4167 hours
Therefore, 25 minutes is the same as 0.0174 days.
minute, in timekeeping, 60 seconds, now defined in terms of radiation emitted from atoms of the element cesium under specified conditions.
So, 7 hours 15 minutes is 7 + 15 ÷ 60 = 7.25 hours.
This online tool will help you convert time given in hours and minutes to decimal hours and/ or decimal minutes. 2 hours 15 minutes is 2.25 hours or 135 minutes.
