In general, Guatemalans also use the metric system, but also some traditional units of measurement (that come from Spain) and influence from US English units. Among the Guatemalan units of measurement some are based on old Spanish units. The libra, arroba, quintal and garrafón units of weight and volume. Guatemalans use also measures like spoons and cups. Therefore, when they weigh the measure of flour, they are using either the ibra, arroba, quintal and garrafón units. Hope this helps.
