- Weights and measures system
- Metric (for distances), Celsius (for temperatures)
- Electricity
- 120-volt system, 60 Hz. Since it is very common to find a ~10volts variation
(110-130), it is advisable to use a surge suppressor. It is common to
find un-grounded
(unearthed) sockets, and unpolarised
plugs. Grounded
(earthed) sockets are usually found in newer buildings which accept grounded
(earthed) plugs. It is not unusual to find the unpolarised, unearthed
sockets for which you will need
an adapter. If you have equipment with European plugs you will need
an adapter
and in some cases a transformer.
Time zone
Monterrey during the Summer months is in the GMT-5 (Greenwich Mean Time
minus five hours) time zone.
