Answer 1

You need to put this in context.

Answer 2

The S.I. system is based on SIX main basic units :-

1.    Length:  metre (m)

2.    Mass:  kilogram (kg)

3.    Time: second (s)

4.    Electric Current: Ampere (A)

5.    Temperature: Celsius / Kelvin (°C / K)

6.    Luminous Intensity: candela (cd).

Some other units also used are :-



1.  Area: square metre (m²).

2.  Volume: cubic metre (m³)

3.   Force: Newton (N) (i.e. kg/m/s²)

4.   Pressure: Newton/sq. metre (N/m²).

5.   Work, Energy, Heat Amount: Joule (J).

6.   Power, Heat flow rate: Watt (W).

7.   Temperature: Celsius (°C Normal use)

8.   Quantity of Electricity: Coulomb (C)

9.   Electro-motive Force: Volt (V)

10. Electrical Resistance: Ohm (Ω)

Conversion - Imperial to S.I.

1 inch (in or "): = 2.54 cm = 25.4 mm.

1 foot (ft or '): = 30.48 cm

1 mile: = 1.609 km

1 mph: = 1.609 kph

1 gallon (gal) = 4.546 litres

*1 ton: = 1016.05 kg  =  1.01605 t

1 pound (lb): = 453.59 g

1 Btu (British Thermal Unit): = 1.055 kJ

1 Therm: = 105.5 MJ

1 kWh: = 3.6  MJ

1 Btu / lb: = 2.326 J / g

1 Btu / ft³: = 37.258 kJ / m³

*1 Long ton = 2,240 lb,   Short ton = 2,000 lb,   Metric ton  =  1,000  kg.

S.I.  to  Imperial.

1 km: = 0.621 miles

1 metre: = 1.093 yards

1 litre: = 0.220 gal

1 kg: = 2.204 lb
