Measures for time, and measures for angles.
The metric unit is a millilitre. The metric unit is a millilitre. The metric unit is a millilitre. The metric unit is a millilitre.
Current is measured in Amperes in all systems of measurement.
Metric unit is easy. Costomary unit is an advanced unit
Kilograms +++ That is the correct metric unit of mass to use, but you would not normally mix unit systems like that. You'd either convert the gallon to litres, or stick to Imperial for both. ' So a gallon of milk (US or UK gallon) weighs a certain number of pounds; a litre of milk weighs a certain number of kilogrammes.
The unit that belongs to both the U.S. customary system and the metric system is the liter (for volume), the meter (for length), and the gram (for mass).
It is the basic unit of time in both systems.
The unit of time ... the 'second' ... is the same in both systems of measurement.
Both. It is the inverse of the unit of time (second) which is used by both systems.
The unit of time ... the 'second' ... is the same in both systems of measurement.
The basic unit of time is the same in both the SI and US systems . . . the second.
Measures for time, and measures for angles.
In the SI - the current metric system - that would be the kilogram. In older metric systems, the gram has been used as the unit of mass.
There are none. The second, although a unit in the SI system is, strictly speaking, not in the metric system since it is based on 60.
In the SI, that is the kilogram. (Older "metric systems" used the gram instead.)
seconds
The only unit that appears in both the modern SI (metric) system and the old fashioned system is the second.
