Estimate lượng nhiên liệu tiêu thụ and chi phí nhiên liệu for a chuyến đi biển from distance, speed, mức tiêu thụ nhiên liệu, and price.
Account for wind, waves, detours, and idling with adjustment factors, and combine round trips or multiple legs in one calculation.

nm
A nautical mile. 1nm equals 1.852km.
kt
A knot. 1kt means 1 nautical mile per hour.
L/h
Fuel use per hour of running time.
L/nm
Fuel use per nautical mile. If you enter distance in km, the công cụ converts it internally to nm first.
Safety factor
A multiplier used to cover wind, waves, detours, and handling losses conservatively.
Often yes. Use the hệ số an toàn to build in a conservative allowance. A rough rule of thumb is Calm 1.05 / Normal 1.15 / Rough 1.30, but adjust it for your own vessel and conditions.
Use L/h when your fuel data is time-based, and use L/nm when your fuel data is distance-based.
Yes. Thêm as many legs as you need, or use the same-distance return-leg shortcut when the outbound and return distances are the same.
It is estimated as a ratio of running mức tiêu thụ nhiên liệu per hour. In L/nm mode, the công cụ derives an L/h equivalent from the weighted tốc độ trung bình.
