"h" : hours
"m" : minutes
"s" : seconds
The following four arithmetic operations can be used to calculate the time. Remember to enter the unit.
1. Addition ex) 1h 25m + 2h 10m = 3h 35m
2. Subtraction ex) 1h 25m-2h 10m = -45m
3. Multiplication ex) 1h 25m × 3 = 4h 15m
(The multiplicand has no unit)
4. Division 1 ex) 1h 25m ÷ 3 = 28m 20s
5. Division 2 ex) 1h 25m ÷ 28m 20s = 3.000
(Fixed to three digits after the decimal point)
Of course, you can also calculate continuously like a normal calculator.
ex) 1h 25m + 2h 10m - 58m = 2h 37m
You can also convert units to days, hours, minutes, and seconds.
ex）1d 2h 3m 5s = s 93785s (to seconds)
m 1563m 5s (to seconds and minutes)
h 26h 3m 5s (to hours and seconds and minutes)
d 1d 2h 3m 5s

h h 26.051h (to hours)
d d 1.085d (to dayss)
Forgetting the unit can result in errors.
In that case, press C (clear) or ← (backspace) button to correct.
ex) 120s + 32 = Error
← s = 2m32s
(120s + 32s = 2m32s)
