On this page, we have compiled the complete list of short tricks and formula for CSAT questions related to Weights and Measurements.

Linear Measurement

• 1 millimetre (mm) = 0.0394 inch
• 1 centimetre (cm) = 10 mm = 0.394 inch
• 1 decimetre (dm) = 10 cm = 3.94 inch
• 1 metre (m) = 100 cm = 10 dm = 39.4 inch = 1.094 yards
• 1 kilometre (km) = 1000 cm = 100 dm = 10m = 10.94 yards = 0.62 miles

Square Measurement

• 1 sq. cm = 0.155 sq. inch
• 1 sq. m = 10000 sq. cm = 1.196 sq. yards
• 1 are = 100 sq. m = 119.6 yards
• 1 hectare = 100 ares (or area) = 2.471 acres
• 1 sq. km = 100 hectare = 0.3386 miles

Cubic Measurement

• 1 cubic cm. (cc.) = 0.061 cubic inch
• 1 cubic m. = 1000000 cc. (1 million cc.) = 1.308 cubic yards

Capacity Measurement

• 1 millilitre (ml) = 0.002 pint
• 1 centilitre (cL) = 10ml = 0.018 pint
• 1 decilitre (dL) = 10 cL = 0.176 pint
• 1 litre (L) = 1000 ml = 1.76 pint
• 1 decalitre (daL) = 10 L = 2.20 gallons
• 1 hectolitre (hL) = 100 L = 22 gallons = 2.75 bushels
• 1 kilolitre (kL) = 3.44 quarters = 2.75 bushels

Weight

• 1 milligram (mg) = 0.015 grains
• 1 centigram (cg) = 10 mg = 0.154 grains
• 1 decigram (dg) = 100 mg = 1.543 grains
• 1 gram (g) = 1000 mg = 15.43 grains
• 1 decagram (dag) = 10 g = 5.64 drams
• 1 hectogram (hg) = 100 g = 3.527 ounces
• 1 kilogram (kg) = 1000g = 2.205 pounds
• 1 tonnes (metric ton) = 1000 kg = 0.984 ton

Time

• 60 seconds = 1 minute
• 60 minutes = 3600 seconds = 1 hour
• 24 hours = 1 day & night = 1440 minutes
• 7 days = 1 week = 168 hours
• 1 month = 30 or 31 days
• 1 year = 12 months = 365 days (leap year: 366 days; february has 29 days)
• 1 decade = 10 years
• 1 century = 100 years

Litre

• 10 ml =1 cL
• 10 cL = 1 dL
• 10 dL = 1 L
• 10 L = 1 daL
• 10 daL = 1 hL
• 10 hL = 1 kL
• 1000 L = 1 kL

Area

• 100 sq. mm = 1 sq. cm
• 100 sq. cm = 1 sq. dm
• 100 sq. dm = 1 sq. m
• 100 sq. m = 1 sq. dam
• 100 sq. dam = 1 sq. hm
• 100 sq. hm = 1 sq. km
• 100 sq. km = 1 sq. miriametre

Volume

• 1000 cubic millimetre = 1 cubic centimetre
• 1000 cubic centimetre = 1 cubic decimetre
• 1000 cubic decimetre = 1 cubic metre
• 1000 cubic metre = 1 cubic decametre
• 1000 cubic decametre = 1 cubic hectometre
• 1000 cubic hectometre = 1 cubic kilometre
