Nicaragua [1] is in standard time zone GMT-6, i.e., six hours earlier than London. Daylight saving time is not observed. During standard time, when it’s 8 p.m. in New York it’s 7 p.m. in Managua [2], and during daylight savings time, when it’s 8 p.m. in New York it’s 6 p.m. in Nicaragua. But no matter what your watch says, you’re always on Nica time—i.e. everything starts a little late and meeting times are considered approximate.
Nicaragua uses the same electrical standards as the United States and Canada: 110V, 60 Hz. The shape of the electrical socket is the same as well. Laptop users should bring a portable surge protector with them, as the electrical current in Nicaragua is highly variable, and spikes, brownouts, and outages are commonplace.
Distances are almost exclusively in kilometers, although for smaller lengths, you’ll occasionally hear feet, inches, yards, and the colonial Spanish vara (about a meter). The most commonly used land-area term is the manzana, another old measure, equal to 1.74 acres. Weights and volumes are a mix of metric and non-metric: Buy your gasoline in gallons, your chicken in pounds, and so on.
