# Time in numbers

Time in terms of seconds, minutes, hours, days and weeks…

Minute:

• 60 seconds

Hour:

• 3,600 seconds
• 60 minutes

Day:

• 86,400 seconds
• 1,440 minutes
• 24 hours

Week:

• 604,800 seconds
• 10,080 minutes
• 168 hours
• 7 days

Equations for time:

S: Second(s), M: Minute(s), H: Hour(s), D: Day(s), W: Week(s)

$S=\frac { 1 }{ 60 } M=\frac { 1 }{ 3,600 } H=\frac { 1 }{ 86,400 } D=\frac { 1 }{ 604,800 } W$

$M=60S=\frac { 1 }{ 60 } H=\frac { 1 }{ 1,440 } D=\frac { 1 }{ 10,080 } W$

$H=3,600S=60M=\frac { 1 }{ 24 } D=\frac { 1 }{ 168 } W$

$D=86,400S=1,440M=24H=\frac { 1 }{ 7 } W$

$W=604,800S=10,080M=168H=7D$
